Sry,just looked punched out and damaged from the Die because of all the Markings,just found it at the bottom...on to the next!
I really Don't Know, I Found it with my Coins.. Whats Crazy is it feels light as a Feather.. I haven't got the chance to go get it tested.. Ireally been enjoying all the old coins and Handmade Carvings I justi inherited a couple month back,I I finally open the box like 6days ago to see what I got..
That is because Cents minted after 1982 were made of Copper Plated Zinc. When the inner Zinc is exposed it erodes away. And your missing part of the Cent so that adds to it feeling lighter... Test? What test? No need for any test, it's just Environmental Damage.
