<p>[QUOTE="bantha421, post: 3574713, member: 104514"]So I thought I would share my methodology for easily telling the difference between a copper/bronze and a zinc penny. This is good for finding the different variants for the 1982 pennies, and to try and find any post 1982 pennies that may have been minted on copper/bronze planchets. </p><p><br /></p><p>Get a known copper penny (1981 or sooner) and a known zinc penny (1983 or later) so you can practice telling the difference. Put the penny on your thumb and flick it into the air, like you're doing a coin toss. The copper/bronze penny will audibly ping/ring while in the air, while the zinc penny will not. Try it a few times until you get the hang of it, but this is a lot easier than using a scale, or a balance. Though this method may not work for the hard of hearing and those lacking in hand-eye coordination.[/QUOTE]</p><p><br /></p>
