The Short Answer
CoinSnap is the most widely used coin identifier app on iPhone, with a 4.7-star rating from more than 300,000 ratings. Coinoscope is the only one that offers unlimited identification for free. For US coins, PCGS CoinFacts is a free, authoritative reference for values and populations, but it does not identify coins from a photo. Coinara, the app we make, is new (4.1 stars from 7 ratings) and is the only identifier here with a $3.99 one-time option instead of a subscription.
1. CoinSnap: The Most Widely Used Identifier
CoinSnap has by far the largest user base in the category (4.7 stars, 309,000+ ratings). The publisher, Next Vision, says it covers more than 240,000 coin types and claims 99% recognition accuracy; that figure has not been independently tested. It also organizes a collection. In-app purchases listed on the App Store run from $3.99 to $39.99.
What we liked
- Large, active user base and frequent updates.
- Collection management alongside identification.
What could be better
- Accuracy claims come from the publisher.
- Full results require a subscription.
Best for: most people who want a mainstream, well-reviewed identifier.
2. CoinIn: Identifier with Buyer and Seller Features
CoinIn (4.7 stars, 102,000+ ratings) identifies a coin from a photo, shows its history and a value estimate, and advertises connections to coin buyers and sellers. In-app purchases range from $6.99 to $49.99.
What we liked
- Highly rated with a large user base.
- Buying and selling features in the same app.
What could be better
- Among the more expensive subscriptions in the category.
Best for: collectors who also want to buy or sell through the app.
3. Coin ID: Identifier with a Collection Organizer
Coin ID from AIBY (4.5 stars, 44,000+ ratings) matches a coin from two photos, then shows size, composition, weight, mintage year and a reference price, and keeps your coins in a collection. Plans run from $4.99 to $7.99 a week or $14.99 to $39.99 a year.
What we liked
- Detailed coin facts and a collection organizer.
What could be better
- Weekly pricing adds up quickly.
Best for: building and tracking a collection.
4. CoinCheck: Identifier with Valuation
CoinCheck (4.5 stars, 12,000+ ratings) identifies a coin from a photo or an image in your gallery and adds a value estimate. Plans are $5.99 a week or $29.99 to $39.99 a year.
What we liked
- Works from existing photos as well as the camera.
What could be better
- Subscription required for full results.
Best for: checking coins you have already photographed.
5. Coinoscope: Free Unlimited Identification
Coinoscope's visual search is free and unlimited; the publisher says value estimates come from eBay and other online listings. Pro plans are inexpensive ($0.99 a month up to a $29.99 unlimited purchase). Its App Store rating is lower (3.3 stars from 134 ratings), so expect rougher results than the most rated apps.
What we liked
- Identification is free and unlimited.
- Cheapest paid tier in the category.
What could be better
- Lower App Store rating.
- Value estimates are based on listings, not only sales.
Best for: occasional identification without paying anything. See also our guide to free coin identifiers.
6. Coinara: Photo ID and Value Estimate (Our App)
You photograph the front and back of a coin, and Coinara returns its name, origin, a short history and an estimated value based on similar coins. It is free to download; results sit behind a $3.99 one-time purchase, a $7.99 weekly plan, a $39.99 yearly plan or a $44.99 lifetime purchase. The app launched in 2026 and has only a handful of ratings so far, so there is little public feedback yet. It is available on iPhone and Android.
What we liked
- One-time and lifetime options if you do not want a subscription.
- Front and back photos, value estimate from comparable coins.
What could be better
- Very few App Store ratings so far.
Best for: someone who wants to check a handful of coins without starting a subscription.
7. PCGS CoinFacts: Free US Coin Reference
PCGS CoinFacts (4.8 stars, 67,000+ ratings) is not a photo identifier. It is a free reference for more than 40,000 US coins with the PCGS Price Guide, population reports, auction prices realized and PCGS Photograde images, and it scans the barcode on PCGS and NGC slabs. The app was last updated in May 2024.
What we liked
- Free and authoritative for US coins.
- Price guide, populations and grading photos in one place.
What could be better
- No photo identification.
- US coins only; not updated since 2024.
Best for: checking the value and rarity of a US coin you have already identified.
8. NGC: Slab Verification and Census
The free NGC app verifies NGC-certified coins by barcode and shows NGC Census population data and NGC Price Guide values for US coins. It is not an identifier either, and its App Store rating is low (2.1 stars from 78 ratings). NGC's website also offers the free NGC Coin Explorer reference.
What we liked
- Free, official NGC certification check.
What could be better
- No photo identification.
- Low App Store rating.
Best for: confirming that an NGC slab is genuine.

What No App Can Tell You
A photo cannot confirm that a coin is genuine, what grade it would receive, or whether it has been cleaned. Those three things decide most of a coin's value. An app's value figure is an estimate for comparable coins, not an appraisal. For a coin that could be worth more than a few hundred dollars, check recent sold results and consider certification by PCGS or NGC.
Which Coin Identifier App Should You Use?
- You want the mainstream choice: CoinSnap has the most ratings and a 4.7-star average.
- You do not want to pay: Coinoscope identifies coins for free; PCGS CoinFacts covers US values for free.
- You do not want a subscription: Coinara has a $3.99 one-time and a $44.99 lifetime option.
- You have a slabbed coin: use the PCGS CoinFacts or NGC app to scan the label.

FAQ
They are good at naming common coins from a clear photo and weaker on worn, ancient and error coins. Accuracy figures such as "99%" come from the app publishers and have not been independently verified. Treat any result as a starting point and confirm date, mint mark and variety yourself.
Most apps show an estimated value based on listings or past sales. That is a range for comparable coins, not an appraisal of yours. Grade, cleaning and authenticity change the price a lot, so check recent sold results (Heritage, eBay sold listings, the PCGS Price Guide) before you buy or sell.
All of the apps in this comparison are free to download. Most limit scans or hide value data behind in-app purchases, which range from about $1 to $50 on the App Store. Coinoscope offers free unlimited identification; PCGS CoinFacts and the NGC app are free reference tools rather than photo identifiers.
No app handles ancient coins reliably, because worn legends and hand-cut dies make photo matching hard. Use an app for a first guess, then confirm the ruler, legend and reverse type against a reference such as Numista or a catalog.
For a coin that might be valuable, yes. If two apps agree on the date, mint and type, the identification is more likely right. If they disagree, the coin needs a closer look or an expert opinion.
