A coin is worth what someone will pay for it. That price depends on date, mint mark, condition, and whether it has any errors or rare varieties. Here is the practical three-step process for getting a real answer in minutes.
Note the date, denomination, country, and mint mark. Mint marks are usually small letters (D, S, P, W, CC, etc.) on the obverse or reverse. The country is identified by the design and language. ErrorHunt can identify the coin automatically from a photo.
Look for anything unusual — doubled lettering, off-center designs, missing elements, extra elements, color differences, weight differences. These are the things that turn a common coin into a valuable one. Use a free coin scanner to check automatically.
Check completed auction prices on eBay, Heritage Auctions, or Stack's Bowers for the same date, mint mark, and grade. Asking prices in price guides are often higher than what coins actually sell for. Recent completed sales tell the truth.
If a coin appears to be worth $200 or more, send it to PCGS or NGC for grading and authentication. The grading fee (typically $25 to $80) pays for itself by giving you a coin you can sell at auction with confidence.
Identify the date, mint mark, and any errors. Then check completed auction sales for the same coin and grade.
If it appears to be worth $200 or more, yes. The grading fee is small relative to the value boost from authentication.
