A friend gave me some old issues of
The Christian Science Monitor dated 1946 which are very interesting to read. I found an article describing how two tons of zinc pennies were about to be dumped into San Francisco Bay.
Sharing the same page were photos of the vice-president in charge of metallurgy and research for the Carnegie-Illinois Steel Corportion, and the newly appointed vice-president of the Bank of The Manhattan Company.
The pennies to be disposed were zinc-coated scrap steel pennies minted in 1943. Since 1982, the United States has minted pennies
as copper-coated zinc wafers. Canada also changed to the primarily zinc penny
in 1997. Check out
this site for more than you probably will ever need to know about zinc! The site is a creation of Theodore Gray (no relation to the late Spaulding Gray).
