Quarters are one of the most collected U.S. coins — and some of them contain valuable mint errors worth far more than 25 cents. ErrorHunt's quarter error checker uses AI to scan your Washington quarters, State quarters, America the Beautiful quarters, and more for known errors and varieties.
Take a clear, close-up photo of both sides of your quarter in good lighting. Upload it to ErrorHunt and our AI identifies any known mint errors, assigns a confidence score, and estimates potential collector value.
ErrorHunt is an AI-powered coin error detection platform designed for collectors, treasure hunters, and anyone curious about the value of their coins.
