4. 1982 NO MINT MARK ROOSEVELT DIME
In the U.S., all coins are printed with a letter indicating the Mint at which they were made. “S” indicates San Francisco, “P” is Philadelphia, and “D” means Denver. (There are some retired Mints as well.) However, in 1982, the Philadelphia Mint forgot to put their identifying mark on a Roosevelt dime, the first error of that kind that was ever made on a U.S. coin. It’s unknown how many were actually distributed, but up to 10,000 of them were found in the Sandusky, Ohio, area after they were given as change at the Cedar Point amusement parks. Though thousands of them were released, a Roosevelt dime lacking a mint mark can sell for up to $300.
Be sure to pass this incredible story along to all of the coin collectors in your life. You never know who could be sitting on top of a potential gold mine and not even know it!
