Frequently asked questions
How do I find out what my coin is worth?
Find the date and the mint mark (a small letter such as D, S or P), then search for that combination here.

Which US coins are worth more than face value?
Any dime, quarter or half dollar dated 1964 or earlier (90% silver), Kennedy halves from 1965 to 1970 (40% silver), 1942 to 1945 war nickels, low-mintage key dates and error coins. See our key dates list and silver coin guide.
