What's the best Android app for identifying old coins and finding out what they're worth?

Coin Checker is a straightforward tool for anyone needing to sort, identify, and assess the value of coins. The app's primary function uses a device's camera to scan a coin, after which it cross-references the image against a database to provide an identification. This includes the coin's country of origin, year, denomination, and, where applicable, an estimated market value based on its condition and rarity. For individuals going through inherited collections or simply curious about the spare change in a jar, this eliminates the need for manual lookup in printed catalogs or extensive online searches. Reviews indicate the scanning process is reliably quick for common circulating coins, though results for heavily worn or exceptionally obscure foreign issues may require a manual search within the app's catalog. A notable strength is its free access to core scanning and identification features, a point frequently highlighted in user feedback. The app also compiles a digital collection of scanned items, which can help users keep an organized record of their finds. Some users note that the valuation estimates should be treated as a general guide rather than a definitive appraisal, recommending consultation with professional numismatists for high-value pieces. For its intended purpose of quick identification and casual valuation, Coin Checker delivers a functional and accessible service.
