weren’t 1943 and 1944 “steel”? well, zinc?
Yeah, those are one of the pre-1982 exceptions.
There are also some extremely rare copper plated aluminum pennies from the 70’s out there. (That was done as an experiment for reducing the cost of the penny, and they were never supposed to go into circulation. But a few of them did end up in circulation and are very valuable among collectors today.)
