The US nickel has been 21.2 mm in diameter ever since 1883.
As nickel was a strategic war material during World War II, nickels coined from 1942 to 1945 were struck in a copper-silver-manganese alloy which would not require adjustment to vending machines. They bear a large mint mark above the depiction of Monticello on the reverse. In 2004 and 2005, the nickel saw new designs as part of the Westward Journey nickel series, and since 2006 has borne Schlag's reverse and Franki's obverse.
