How it works
From an unknown coin to a saved find.
A simple flow for the moment a coin makes you wonder.
Identify
Get the coin's name, country and year, with a match score.
Estimate
See an estimated value range and the coin's condition grade.

Made for coins
One app, from the first look to the collection.
AI identification
Two photos, one clear answer.
Photograph the front and the back. Coin Finder reads the inscriptions and the design, then gives you the coin's name, country and year with a match score. When it is not sure, it says so and shows what else the coin could be.
Value, grade and rarity

Each result comes with an estimated value range, a condition grade and a rarity level, with the varieties and mint errors to look for. It is an indicative estimate, not a professional appraisal.

Questions
Good to know before you scan.
What can Coin Finder identify?
Coin Finder is made for coins. It analyzes photos of both sides and suggests the most likely match, with a match score. When it is not sure, it tells you and may show other possible matches. Some coins cannot be identified from photos.
How do I get a better result?
Place the coin on a plain, dark surface. Use even light and avoid reflections. Fill the frame and keep the coin sharp. Photograph both sides.
Are value estimates professional appraisals?
No. Values, grades and rarity levels are indicative estimates generated by AI from your photos. They are not an appraisal, an authentication or an offer to buy. For a valuable coin, ask a qualified numismatist or a professional grading service.
Can I use Coin Finder for free?
The app is free to download and your first scan is free: it shows the identification and details of your coin. The estimated value, grade and rarity, further scans and the collection require a subscription.
Where do I manage my subscription?
In your Apple or Google account settings, or from the app under Settings > Manage subscription. Cancel at least 24 hours before the end of the current period to avoid the next charge.
