Hi All, I am new to coin collecting and am focusing on small cents (Lincoln 1909-present). I came across this 1990 Lincoln Memorial cent and noticed it had a weird radial double stamp effect. The "E PLURIBUS UNAM" seems to be doubled and the "UNITED STATES oF AMERICA" and "ONE CENT" seem also to be doubled going in the outer direction with the memorial and lettering missing plating in the doubled area. Any thoughts or has anyone seen this before and can explain whats happening? Thanks for helping out a new user!
