Hi everyone I get this 1970 S Lincoln cent it looks like doubled mint =mark is't I need your help thanks.
That one appears to be machine doubling.
You can review known RPM's here.http://www.varietyvista.com/02b LC RPMs Vol 2/RPMs 1970S.htm
That would be machine doubling, it is super common and adds no value to the coin.
One cent worth one cent.
Not a doubled mint mark, no numismatic premium. Cheers, RickO
