First thanks to all that replied to my first post I am a noob but interested lol second I thank all who give wisdom again.
There are lots and lots of coins out there with mechanical doubling and die deterioration that can appear to be doubled. true hub doubling isn't very common. The following sites have listings of known doubled dies. Www.doubleddie.com Www.varietyvista.com Doubleddie.com also has a section called "Worthless doubling" which gives a good explanation of mechanical doubling
In my opinion, and everyone has one, cents minted after 1982 aren't worth the time unless you are looking for something to do with your spare time. JMHO.
