U.S. Mint coin reference

Obverse: Thomas Jefferson portrait.
Reverse: Monticello.
After the wartime alloy ended, the Jefferson nickel returned to its standard copper-nickel composition in 1946. Felix Schlag's Monticello reverse remained the regular design through the end of the twentieth century.
Mintmark placement changed over this long span, proofs and circulation strikes were made in different periods, and step detail varies sharply. Those facts are more useful than treating every coin from 1946-2000 as identical.
