World War II copper shortages forced the use of zinc-coated steel pennies in 1943. However, some were misminted in copper. These rare items can cost thousands.
The writing and date on this cent are doubled. Collectors prize it and pay a lot.
Like the 1955 doubled die, this 1972 penny doubles the inscription and date. Another excellent treasure if you find one.
Several pennies were mistakenly struck on copper planchets instead of zinc-coated ones in 1983. These are rare and valuable.
The reverse (tails) side of the coin was changed in 1992 to "Close AM" and "Wide AM" varieties. Rarer and more expensive is the Close AM.
The date and "LIBERTY." double on this penny. Another valuable mistake coin that collectors want.
