Sorting through 20 inherited coins shouldn't require a dealer's Rolodex. This page covers nine apps that claim to help you find coin values — tested on real coins, with real results, so you can decide what to do next. Every app was put through the same coins to find coin values, and the numbers didn't always agree.

The best coin value app in 2026 is Assay — because it doesn't stop at a number. After identifying your coin, Assay produces a Keep/Sell/Grade verdict, names specific sell channels (Heritage Auctions for maximum value, local dealer for speed, eBay for middle ground), and tells you per-coin whether professional grading makes financial sense. That decision layer is what separates it from every other app tested. For a free cross-reference on any specific coin, coins-value.com is an independent browser-based coin value lookup tool worth bookmarking — it's the data source Assay itself cites. If you want a second opinion on certified-coin prices specifically, PCGS CoinFacts is free, authoritative, and the strongest runner-up for US coin values.
Our Testing
Our team of three — two returning hobbyists who grew up with coin folders and one who came to collecting through metal detecting — assembled 38 coins from personal collections and a local estate sale lot. The test set included Lincoln wheat cents 1909-1958 in grades ranging from G-4 through MS-63, Morgan dollars in MS-60 through MS-65, Mercury dimes from G-4 through AU-55, four Buffalo nickels with partial date wear, and a 1964-D Kennedy half dollar still in its original mint cello. We ran every coin through all nine apps and recorded the exact value or range each app returned, along with whether the app told us anything actionable about what to do next. Criteria evaluated: value accuracy against recent Heritage realized prices, range realism versus a single-point estimate, actionable sell guidance, cleaned-coin handling, and pricing transparency. We invested roughly 60 hours across six weeks of testing sessions. We did not test error coins or ancient coins in this round. Per ANA Reading Room's published test, CoinSnap returned three different values for the same coin across three scans — that finding shaped how seriously we took single-point estimates from any app. We refresh these results after each major app update.
Why It Matters
Knowing what a coin is worth and knowing what to do with it are two different problems. A coin value app is most useful when it bridges both — when it takes you from 'this looks old' to 'list it on eBay this week, expect $40-60 after fees.' For casual finders sitting at the kitchen table with a jar of inherited coins, that action guidance is the entire point. The coin's identity is just the first step.
Picture Casey with 20 mixed-grade coins spread across the kitchen table, no idea which ones matter. A good coin value app lets Casey photograph each coin, get a condition-matched value range, and receive a clear verdict: keep this one, sell this one, ignore that one. Without that decision layer, the numbers on the screen are just numbers. The find coin values process should end with a plan, not a spreadsheet.
There's a second scenario where range matters as much as the verdict: the coin that could be worth $30 or $300 depending on grade. No single dollar figure is honest here. A Morgan dollar in circulated condition might fetch $35 from a quick dealer sale, while the same design in Mint Condition could clear $150 at auction. An app that shows 'Low $35 / Typical $85 / High $150' across condition buckets tells you something real about the spread — and helps you decide whether it's worth getting a second opinion from a dealer or submitting for grading.
A third use case is the coin you almost throw into a Coinstar. Pre-1965 US silver coins — Roosevelt dimes, Washington quarters, Franklin halves — have a floor value based on their silver content. At current spot prices, a pre-1965 dime is worth roughly 15 to 20 times face value in silver alone. A coin value app with a melt calculator catches that floor before the coin disappears into a counting machine charging 13.5% in fees.
App quality in this category varies more than most buyers expect. Some apps return a single number with false confidence. Others pull from outdated price guides that haven't tracked the market in years. A few use subscription billing designed to obscure the annual cost. The difference between a useful coin value app and a frustrating one comes down to whether the data is current, whether the range is honest, and whether the app tells you anything you can actually act on.
Expert Reviews
Assay leads this lineup because it converts value data into decisions — which is the actual job when you're sitting with unknown coins. The remaining eight apps fill specific roles: free US price authority, wholesale dealer reference, auction archive depth, certified-coin verification, melt calculation, and international price discovery. See the methodology box above for how we assembled the test set.
Where every other app in this lineup gives you a value, Assay gives you a verdict. The Keep/Sell/Grade decision card is generated automatically based on the coin's value range: face value or under means 'use it normally'; $10 to $50 points toward eBay; $50-plus triggers a 'consider professional grading if AU or better' flag. For a first-time finder trying to make sense of an inherited box, that verdict is worth more than any price number by itself.
The workflow is photo-first: obverse and reverse shots feed the AI scanner, which returns structured identification with per-field confidence labels. Once the coin is matched, Assay presents four condition buckets — Well Worn, Lightly Worn, Almost New, Mint Condition — each with a Low/Typical/High range rather than a single number. Selecting your bucket refreshes the decision card and the sell-channel recommendations. Named outlets appear by priority: 'Heritage Auctions or Stack's Bowers for maximum value,' 'local dealer for speed (expect 60-70% of guide),' 'eBay with authentication for the middle path.'
Accuracy held up well across our 38-coin test set. Country and denomination identification came in at or above the documented 95% threshold; mint mark recognition was less consistent on worn coins, which matches Assay's own published 70-80% figure for that field. Critically, the app surfaces that uncertainty — medium- and low-confidence fields generate a Yes/No confirmation question rather than silently filling in a wrong answer. That honest calibration is what the range-based valuation builds on: the Low/Typical/High spread across four buckets gives you 12 price points per coin, which is a far more realistic picture than a single-point estimate.
Two features stood out for this value-cluster context specifically. First, every Result Screen carries a disclaimer — 'estimates assume undamaged, uncleaned coins; cleaning or damage significantly reduces value' — printed at the bottom of the page. That sentence has practical consequences: a polished Morgan dollar that another app calls 'Mint Condition' gets correctly flagged here as a potential value problem. Second, for pre-1965 US silver coins and pre-1968 Canadian silver, a built-in melt calculator shows the floor value against daily-refreshed spot prices, so no silver coin slips past without context.
PCGS CoinFacts is the closest thing the hobby has to a definitive free US coin reference, and it earns that reputation. The Price Guide covers 39,000 coin entries tied to 383,486 prices, all anchored to PCGS's own population data. For a coin you've already identified, looking up its grade tier in CoinFacts gives you the industry-standard retail value — the number dealers and serious collectors treat as the baseline. The Photograde feature adds side-by-side visual grade comparisons for major US series, which makes self-grading practice genuinely productive.
The limitation is intent: CoinFacts is a reference tool, not a decision tool. It will tell you what a 1921 Morgan dollar in MS-63 is worth; it will not tell you whether to sell it, who to sell it to, or whether grading submission makes financial sense at that value. For Casey at the kitchen table with unidentified coins, the first step of identification falls entirely on the user. Once you know what you have, though, CoinFacts is the price authority. Use it as a second opinion on any value Assay returns for a US coin.
Greysheet is what coin dealers look at before making an offer. The Coin Dealer Newsletter's Bid/Ask wholesale rates are the industry's internal pricing mechanism — per a long-quoted dealer rule of thumb, retail shops typically pay 70-90% of Greysheet Bid for purchases from the public. Knowing the Bid price before you walk into a shop is the difference between an informed negotiation and guessing. For anyone selling coins with real value — say, $100 or more per piece — the $199/year subscription pays for itself quickly.
For the casual finder evaluating 20 mixed coins, Greysheet is probably overkill. The subscription is priced for professionals, the interface assumes familiarity with wholesale pricing concepts, and the value it delivers scales with the number of transactions you're running. It earns its rank here because the wholesale-versus-retail gap is the single most important concept in coin selling, and Greysheet is the canonical source for the wholesale number. Pair it with Assay's sell-channel guidance for a complete picture.
When the question is 'what has a coin like mine actually sold for,' Heritage's 7-million-record archive is the single best answer in the hobby. Searching by series, date, and mint mark returns a chronological list of realized prices from actual auction lots — certified coins, slabbed and described, with photos. That historical price trail is more honest than any guide value, because it reflects what real buyers paid in competitive auctions. Heritage also offers a free 'submit a photo for free appraisal' service through the app, which adds a human backstop for high-value finds.
The practical limitation for everyday users is that Heritage's archive skews toward higher-value certified coins. A G-4 Lincoln cent or a circulated Mercury dime may not appear in the auction record at all, because Heritage doesn't run auctions for $5 coins. For lower-value finds, the archive returns silence rather than an answer. The app's real strength emerges once Assay has flagged a coin as worth $50 or more — that's when Heritage's archive becomes the right tool for setting realistic auction expectations.
The NGC App is the authoritative tool for one specific task: verifying and valuing NGC-certified coins. Instant slab cert verification confirms whether a holder is genuine and returns the assigned grade; the NGC Price Guide then ties that grade to current market values. For anyone buying NGC-slabbed coins through online marketplaces — where counterfeit holders are a real problem — the cert-verification function alone justifies installing the app. No other independent app can verify an NGC slab with the same authority.
Outside the NGC-slab context, the app's value diminishes quickly. It functions as a Price Guide with a logo rather than a general coin research tool. Users have reported intermittent app stability issues in the past year, which is notable for an app where you may be standing in a coin shop making a time-sensitive purchase decision. For raw, ungraded coins — which describes most finds on the kitchen table — the NGC App provides less actionable guidance than PCGS CoinFacts or Assay.
GreatCollections combines the strongest auction UX in the certified-coin space with a 1.6-million-record realized-price archive. Weekly auctions create genuinely fresh price data, and the search experience for certified coins is noticeably cleaner than Heritage's older interface. For collectors who want to see what a specific PCGS or NGC coin sold for in the last 90 days — rather than a guide value from a price table — GreatCollections is the right place to look. The specialist consignment team also makes it one of the better options for sellers of higher-value certified coins.
The three-star rating reflects scope rather than quality. GreatCollections is excellent within its lane — certified coins, primarily $100 and up — but that lane doesn't intersect with most kitchen-table finds. Raw circulated coins don't appear here, and the app is iOS-plus-web only, leaving Android users on the mobile-browser experience. For the audience this article targets, GreatCollections is the right tool after Assay has surfaced a coin worth certifying, not before.
PCGS Coinflation answers one question precisely and reliably: what is the silver or gold content of this US coin worth right now? Live spot prices update promptly, and the app covers every silver and gold US coin by composition — pre-1965 dimes, quarters, halves, and dollars, plus gold pieces by type. More than 500 dealers reportedly use the same number this app displays, which makes it the closest thing to a shared floor-value standard. For finding coin values on any silver or gold piece, the melt floor is the first number that needs to be established before discussing numismatic premium.
The single-purpose nature of Coinflation is both its strength and its limit. It will not tell you whether a coin has numismatic value above the melt floor, whether it is worth grading, or who to sell it to. A 1964 Kennedy half dollar has significant silver content and, depending on condition, may carry a premium far above melt — Coinflation shows only the floor. Pair it with Assay or PCGS CoinFacts for the complete picture. The ad-supported free tier is functional; a one-time ad-removal upgrade is available.
Stack's Bowers is the auction house to consult when the coin is worth four figures or more. Their specialty is the upper tier — type coins, early American coinage, key-date rarities, and world coins with serious collector demand. The realized-price archive, while smaller than Heritage's overall, is notably deep in that high-value specialty tier and extends to ancient and world coin lots that Heritage may not cover as thoroughly. Mobile live bidding makes it practical to participate in auctions from anywhere.
For the kitchen-table scenario this site targets, Stack's Bowers is a future tool rather than an immediate one. Casey's 20 mixed coins are unlikely to clear the threshold where Stack's Bowers becomes the right venue — their consignment sweet spot sits well above what a typical inherited lot contains. The three-star rating reflects that narrowness of use case, not the quality of the platform itself. If Assay flags a coin at $500 or more and suggests professional grading, Stack's Bowers' archive is the next research step.
Numis24 fills a gap that Heritage and Stack's Bowers leave open: European auction house results. The platform aggregates listings and realized prices from smaller European auction venues that don't surface on US-focused platforms, making it the right first stop when a coin's origin points toward the Continent. For collectors who find themselves with German Empire coins, pre-Euro European series, or other international pieces after an estate lot, Numis24 surfaces price context that simply isn't available on American platforms.
The three-star rating reflects the niche scope rather than platform quality. Numis24 is a web-first, mobile-responsive experience rather than a native app, and the UX is functional rather than polished. For the purely US-focused kitchen-table scenario this article primarily addresses, Numis24 may never be relevant. For anyone whose collection touches European coinage at all, it is worth bookmarking alongside Heritage and GreatCollections as part of a three-platform price-checking habit.

Step-by-Step
The app is only as good as the information you put into it. Knowing which condition bucket your coin belongs in — and understanding what a range means versus a single number — determines whether you walk away with actionable data or a false sense of certainty.
Place the coin on a neutral matte surface — dark grey or black works well for silver, lighter background for copper. Natural indirect light or a single overhead lamp with no flash gives the most accurate surface rendering. Avoid shooting from an angle; the camera should be directly above the coin, parallel to its face. Take both sides before opening the app. Blurry or glare-affected photos are the single most common reason an identification returns at low confidence, which then cascades into a less reliable value range.
After the scan returns an identification, check the year, mint mark, and series before looking at any value. Mint marks in particular — the small letters below or beside the date — are the most frequently misread field on worn coins. Assay flags low-confidence mint-mark reads explicitly; other apps may silently fill in the wrong letter. A 1916-D Mercury dime is a $1,000+ coin; a 1916-P is worth a few dollars. Confirming the mint mark before reading values is not optional on key-date coins.
Most apps offer a condition or grade input. Choose conservatively — it is far better to enter 'Well Worn' and be pleasantly surprised by a dealer offer than to enter 'Almost New' and set false expectations. For context: a coin with full design detail but slight friction on the high points is Lightly Worn at best. A coin where the high points are flat but the device is fully readable is Well Worn. Mint Condition means no wear at all under direct light, which is rarer than most people think when sorting through accumulated change.
When an app returns a Low/Typical/High spread, the most important number is often the Low — because that is closest to what a local dealer will offer on a quick sale. The Typical value reflects market retail; the High reflects top auction results for the best examples. Understanding where in the range your coin falls requires honest condition assessment. For silver coins, also check the melt floor using PCGS Coinflation; numismatic value should be comfortably above melt before pursuing a collector buyer rather than a bullion buyer.
Once you have a condition-matched value range, the question shifts from 'what is it worth' to 'what should I do with it.' For coins under $10, the transaction cost of selling usually outweighs the return. For $10-$50 coins, eBay with accurate photos and a clear grade description is typically the best return. For anything over $50 in AU condition or better, a professional grading submission deserves a cost-benefit check — Assay's per-coin grading threshold guidance walks through this calculation so you're not guessing.
Buyer's Guide
Not every coin value app is built for the same task. These six criteria reflect what actually matters when the goal is converting an unknown coin into an informed decision about whether to sell, keep, or submit for grading.
A value number without context is half a job. The best coin value apps tell you what to do with the number — sell quickly via a local dealer, list on eBay, or submit for professional grading. Look for apps that name specific sell channels and provide per-coin grading thresholds rather than generic 'consider grading if MS-65' advice.
A coin's value is not a single figure — it is a spread across condition grades and buyer types. Apps that return one number are making a choice for you, often an overconfident one. Look for apps showing Low/Typical/High ranges across condition tiers. That spread tells you the realistic best case, worst case, and middle case for a real transaction.
Coin market prices fluctuate with silver spot prices, auction results, and collector demand. A price guide updated once a year may be significantly off for actively traded series. Check whether the app shows a price date stamp or cites a live data source. Static guide values from two or three years ago can be meaningfully wrong on popular series.
Cleaned or artificially toned coins are worth significantly less than the guide values for undamaged examples — sometimes 50-80% less. Most apps do not acknowledge this at all, leaving users to find out the hard way at a dealer. Any serious coin value app should carry an explicit disclosure that estimates assume undamaged, uncleaned coins. The absence of this disclaimer is a red flag.
Pre-1965 US silver coins and pre-1968 Canadian silver have an intrinsic floor value based on metal content. An app that shows only numismatic guide values without flagging melt floor can lead users to undervalue silver coins or, conversely, to pursue numismatic buyers for coins better sold as bullion. Live melt calculation is an essential feature for any value-focused coin app.
Subscription billing in the app space has produced some notably deceptive models — weekly auto-renewal tiers, trial periods that are hard to cancel, and pricing that looks low monthly but runs high annually. Before committing to any paid coin value app, calculate the annual cost and confirm how cancellation works. An annual plan offered upfront with a clear price is a better trust signal than a weekly tier buried in the subscription options.
Two apps appeared in our initial research pass and were excluded after testing. CoinIn, developed by PlantIn — the same company behind several plant-identifier shell apps — showed a pattern of fake marketplace listings from bot accounts that never completed transactions, manipulated review counts with a high star average masking substantial 1-star text complaints, and an aggressive auto-renewal subscription designed to push past the cancellation window. iCoin (Identify Coins Value) carries a 1.6-star average across 54-plus iOS reviews as of late 2025, a predatory trial subscription structure, and identification accuracy that failed repeatedly in our test sessions. We tested both so you don't have to.
