I have a 1983 Mint Proof set with an error on the
Lincoln Penny. I am new to collecting and need some info. I tried to take pictures but not large enough or clear. The S mint mark has a double stamp. I took this set to two coin dealers and they agree with the error. My question is should I send this out for grading in the whole set or take the penny out and send it. Where should I send it, any suggestions would be appreciated.
