Homebrew PCBs

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.
