Die rotations cause coins to be minted with the reverse or obverse of the coin partially or fully rotated. A die rotation occurs when the dies become loose and they then turn.

A doubled die occurs when a die receives an additional, misaligned impression from the hub. Overdate coins such as the 1942/1 U.S. Mercury dime and 1918/7 U.S. buffalo nickel are also doubled dies.

The Uncirculated Mint Set was introduced in 1947, containing two examples of each coin issued for circulation packaged in a cardboard display case. The reason for this was so that collectors could display both the obverse and reverse of each coin in the set's packaging, which allowed only one side of the coin to be displayed.
