About valuesAll values are estimates. Prices depend on condition (grade), variety, eye appeal and the market at the time of sale, and an app scan or a guide is not an appraisal. If a coin may be valuable, have it authenticated and graded by a professional grading service or a reputable dealer before you sell or buy it.
Check your coin in seconds
Coin Scanner identifies a coin from a photo of both sides, reads the date and mint mark, and gives an estimated value range so you know whether it deserves a closer look.
