Use photo analysis for possible matches across US coins, euros and world currencies described in the listing.
Coin collecting and visual research
A small coin. A better set of questions.
Use Coin ID to explore possible coin identities and information about origins, composition and history. Organize a digital album while treating suggested grades, unusual marks and values as information to check.
Some features may require an in-app purchase or subscription. Check the App Store for current availability and pricing.
Inside the app
Look closer at the details
Explore information about mint marks, possible manufacturing errors, historical context and composition without treating suggestions as certification.
Organize your coin album
Keep a digital collection and view value estimates, remembering that a displayed total is not a cash balance or a sale offer.
Coin ID
How it works
Capture both faces
Make clear overall photographs and relevant detail images, keeping the same coin linked across views.
Read before naming
Record visible text and marks, then compare the suggested identity with an appropriate reference.
Keep conclusions provisional
Organize the record and label any grade, error or value suggestion as unverified unless independently assessed.

Identification, grade-related estimates and possible error suggestions may be wrong. Coin ID is not certified grading, authentication, appraisal or financial advice. Displayed values are not guaranteed sale prices. Feature access and any paid options depend on current in-app terms.
- Does a scan authenticate a coin?
- No. A photo match cannot certify authenticity, a grading level or a minting error. Seek appropriate examination when those questions matter.
- Is the estimated value an offer?
- No. The listing describes estimates, not a promise to buy or a guaranteed selling price. Do not treat a collection total as money available to spend.
- Which coins are described?
- The supplied listing mentions US coins, euros and world currencies. It does not guarantee a correct match for every design or issue.
- Are there paid features?
- The supplied description does not detail paid access. Check current in-app terms and purchase information for the options you need.
