How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Photo identification is mostly accurate on modern US coins, around 90 percent or better in independent tests, but weaker on worn, ancient or foreign coins.
- Value estimates from scanners skew optimistic, because they assume a better grade and variety than a phone photo can confirm.
- For trustworthy value, the free PCGS and NGC price guides beat any scanner estimate, and recent sold listings show what buyers actually pay.
- Never clean a coin that might be valuable: cleaning strips the original surface and a cleaned coin sells for far less than an untouched one.

The best coin value app
Starting priceFree
Free planYes
CoinSnap is the easiest starting point for a beginner with a jar of coins. Point the camera, get an identification, and see an estimated value in seconds. Comparisons rate it near the top for US identification accuracy, and the free tier allows 10 scans a day, which covers a casual sorting session.
The limits are value, not identification. Full features need a subscription, grading estimates are basic, and the value figure assumes a grade your photo cannot prove. Use CoinSnap to identify, then check the PCGS or NGC guide for the actual grade price before believing a high number.
What we like- Most accurate US identification in comparisons
- 10 free scans a day
- Simple point and shoot flow
Watch out for- Full features need a subscription
- Grading estimates are basic
- Value figures skew optimistic

Free planYes
Coinoscope is the best free tier for identification, with unlimited scans covering US and world coins, plus offline basic functions for estate sales or flea markets without signal. The visual database spans coins from virtually every country, and each match brings historical context that explains why certain dates or varieties command higher prices.
Value features are the weak point: estimate value and advanced image analysis are free only with daily limits, and the value ranges are broad. A Pro version removes ads and limits. For identifying a mixed world collection for free, Coinoscope is the pick, paired with a price guide for value.
What we like- Unlimited free scans
- Covers US and world coins
- Works offline for basic functions
Watch out for- Value ranges are broad
- Extra features like value estimates have daily limits
- Pro needed for unlimited advanced analysis

PCGS CoinFacts
Best for: Authoritative US reference data
Visit pcgs.com
Starting priceFree
Free planYes
PCGS CoinFacts is the reference every serious US collector should have, and it is fully free with no ads. It offers encyclopedic US coin data, a Photograde visual reference for grading, and a price guide broken down by grade, which is exactly the information a scanner estimate cannot give. If a scanner says a coin is worth hundreds, CoinFacts shows what that coin is worth in each grade, so you can judge honestly.
It does not identify coins from photos, and its focus is US coins rather than world issues. Pair it with CoinSnap or Coinoscope: identify with the scanner, value with CoinFacts. That two step flow is the most trustworthy free method in this list.
What we like- Fully free with no ads
- Authoritative US coin data and Photograde reference
- Price guide by grade
Watch out for- No photo identification
- US focused, not world coins
- Research tool, not a scanner
Starting priceFree
Free planYes
The NGC Coin App does one job extremely well: verifying coins already graded and sealed by NGC. Scan the barcode on an NGC holder and you get the grade, census population, NGC Price Guide value, and for most coins graded since 2008, actual photos of your specific coin from NGC archives. Population data updates weekly, so rarity by grade is current.
It cannot help with raw coins, since it has no photo identification, and users report crashes during searches. If you buy or own NGC slabs, download it before handing over money, since confirming a slab against the database is the best fake check available. For raw coins, pair it with a scanner app.
What we like- Verifies NGC slabs against a database of nearly 20 million coins
- Population reports by grade
- NGC Price Guide values
Watch out for- Only works for NGC certified coins
- No identification for raw coins
- Users report crashes during searches

CoinKnow earns the accuracy crown in recent comparisons, with a grading range of 2 points, tighter than rivals at 2 to 3 points, plus automatic error detection and multi source pricing. It also auto detects copper and Proof issues, which many scanners miss, and it suits beginners who want a grading estimate they can lean on more than a single optimistic number.
The app is newer, so its community and database depth trail PCGS and NGC, and its focus is US coins. Some advanced features sit behind a paid tier. For a US collector who wants the best grading estimate from a phone photo, CoinKnow is the current pick.
What we like- Tightest grading range at 2 points
- Auto detects errors, copper and Proof issues
- Multi source pricing
Watch out for- Newer app with smaller community
- US focused
- Some features need a paid tier

Coin Value Checker is the most feature complete free option in recent comparisons, combining identification with error detection, market trends, auction alerts and portfolio tracking. For a collector who follows the market rather than just identifying coins, the trend and alert features add real value beyond a one time scan.
Grading accuracy sits at a 2 to 3 point range, slightly looser than CoinKnow, and market data quality varies by coin, with common coins covered better than obscure ones. Some comparisons also note an Android focus. For a collector who wants market intelligence in the same app as identification, this is the pick.
What we like- Most feature complete free option
- Error detection and market trends
- Auction alerts and portfolio tracking
Watch out for- Android focused in some comparisons
- Grading range of 2 to 3 points
- Market data quality varies by coin

Greysheet Mobile is the pricing reference dealers use, and it belongs in a serious collector toolkit for that reason. It gives wholesale pricing that reflects what dealers pay each other, which is the realistic floor when selling to a shop. For a collector deciding whether to sell to a dealer or list privately, that wholesale figure sets expectations honestly.
It does not identify coins or grade them, and wholesale prices sit below retail prices, so a beginner may mistake a Greysheet value for a selling price. Use it alongside an identification app and a retail guide: identify, check retail in PCGS or NGC, then check wholesale in Greysheet to see the dealer spread.
What we like- Wholesale dealer pricing reference
- Trusted by serious buyers and sellers
- Compact mobile reference
Watch out for- No identification or grading
- Wholesale prices differ from retail
- Dealer focused interface
#8
Heritage Auctions
Best for: Real sold prices at auction
Visit ha.com
Starting priceFree
Free planYes
Heritage Auctions takes a different approach to value: it shows what coins actually sold for at auction, not estimated book values. Searching the archive for a coin identical to yours, in the same grade, gives genuine market data based on what collectors are willing to pay right now. Upcoming auctions and in app bidding extend the tool from research to buying.
Auction prices include buyer premiums and fees, so a hammer price is not the seller net, and the archive skews toward valuable coins rather than common change. Still, for a coin that might be genuinely valuable, a Heritage sold listing beats any scanner estimate. Check sold prices before you accept a dealer offer or list a coin yourself.
What we like- Shows what coins actually sold for, not book estimates
- Deep archive of past sales
- Upcoming auctions and bidding in app
Watch out for- Auction prices include buyer premiums and fees
- No identification
- High end bias toward valuable coins
How we chose
We compared identification accuracy claims, grading ranges, pricing sources and free tier terms from independent comparisons published in 2026, and we weighed US against world coverage, scanner estimates against guide prices, and dealer against retail pricing. We favored apps with a usable free tier and honest value sourcing, and we flagged where scanner estimates skew optimistic. No tool was credited with hands-on testing, and no user counts, awards or ratings were invented for this guide.
What to check before you trust a value
Start with identification, then grade, then price, in that order. A scanner can identify a coin correctly and still overvalue it, because value lives in grade and variety, which a phone photo cannot confirm. Check the price for the actual grade in the PCGS or NGC guide, and compare with recent sold listings on Heritage or eBay before believing any high number.
Next, never clean a coin that might be valuable. Cleaning destroys collector value by stripping the original surface, and a cleaned coin sells for far less than an untouched one. Leave the coin alone and let a professional grader assess it if the guide value justifies certification. For a coin that really is valuable, PCGS and NGC both accept submissions through membership or an authorized dealer, and a local dealer or coin club will usually give a free opinion first.
Finally, know your selling channel. A dealer pays wholesale, an auction brings retail minus fees and premiums, and a private sale sits between them. Greysheet shows the wholesale floor, Heritage shows auction reality, and the guides show retail book value. The right price depends on which channel you actually use.
Frequently asked questions
What is the best free coin identifier app?
Coinoscope for a free tier that identifies both US and world coins with unlimited scans, and CoinSnap for the most accurate US identification, though its full features need a subscription. For value, the free PCGS and NGC price guides are more trustworthy than any scanner estimate.
Are coin identifier apps accurate?
At identification, mostly yes on modern US coins, around 90 percent or better in independent tests, and less so on worn, ancient or foreign coins. At grading and valuation, no, and that is the part that decides what a coin is worth, so confirm value against a price guide and recent sold listings.
Why does the app say my coin is worth a lot?
Because the estimate assumes a better grade and variety than a phone photo can confirm, and these apps skew optimistic. Check the price for the actual grade in the PCGS or NGC guide and look at recent sold listings before you believe a high number.
Should I clean a coin before selling it?
No. Cleaning destroys collector value by stripping the original surface, and a cleaned coin sells for far less than an untouched one. Leave any coin that might be valuable alone and let a professional grader assess it.
What is the difference between wholesale and retail coin prices?
Wholesale, shown by Greysheet, is what dealers pay each other, while retail, shown by PCGS and NGC guides, is what collectors pay dealers. A dealer offer will sit near wholesale, an auction result sits near retail minus fees, and a private sale usually lands between them.
When should I get a coin professionally graded?
When the guide value in a high grade justifies the grading fee, or when authenticity is in doubt. Certification protects value, makes selling easier, and gives a population count that proves rarity. For common coins worth a few dollars, grading costs more than the coin.
