My site,
www.coppercoins.com offers free self-identification of
Lincoln Cent die varieties as of present. In the future I will be placing thousands of photos of other series, starting with
Mercury dimes and Buffalo and
Jefferson nickels onto uscoinvarieties.com (not currently operational), which will eventually house die variety identification information for all
US coins. Just thought I would post it so people here could be aware they are out there.
