Leon,
Not sure where you got this. The last--only--(USA)steel pennies were
made in 1943.
In 1981 they were changed to copper plated Zinc, due to a law which
requires that the inherent metal value cannot exceed the currency
value.
I just checked several, from 1984 to 2004(Denver minted), and none
were attracted by the magnet.
