What this site is
Coin Identifier publishes guides on identifying and valuing US, world and ancient coins: how to read dates and mint marks, how to tell an error from damage, and how to check a value against recent sales. It is the editorial site for Coinara, an iPhone app that identifies a coin from photos of both sides and estimates its value from comparable coins.
Start with the coin value checker, the old coin identifier guide or the coin identifier app comparison.
Who is behind it
Coin Identifier and Coinara are made by OBZENA LLC, a Wyoming, USA limited liability company. Because we make Coinara, our guides recommend it; the app comparison lists the alternatives with their public ratings and prices.
How the content is made
Guides are drafted with the help of AI writing tools, working from PCGS and NGC references, auction records and mint publications, and edited by the Coin Identifier Editorial Team. We do not publish first-hand test claims or personal author personas. The full policy is on How we create content.
Values are estimates for comparable coins, not appraisals. Identifications and values in the app are produced by AI models: useful starting points, not a professional opinion. For a high-value coin, consult a grading service such as PCGS, NGC or ANACS before buying, selling or insuring it.
If you spot an error, send us a correction. We correct confirmed errors and update the page's date.
