When in 1982 did the change from copper to zinc happen? If it was
early in 1982, then I would think there would be little chance of a
copper 1983 cent.
But I have wondered about it and other composition errors that might
exist, such as steel 1944 cents, silver 1965 dimes/quarters/halves,
40% silver 1971 halves or 35% silver 1946 nickels.
According to the website below, the change took place around mid 1982,
this was the only thing could find close to a date. So I would say
during the summer of 1982.
I probably should include the website.
