Here's a site to check it with: http://www.doubleddie.com/754502.html Or this site: http://varietyvista.com/06 Mercury Dime/RPMs 1941D.htm
Hi Charlie, Imho, @thomas mozzillo has added some helpful links on rpm for mercury dimes. I looked for other sites but it doesn’t seem like anyone has developed a site dedicated to only Mercury dimes varieties and errors . However I did manage to find a few books that may have a lot more information. Bowers, Q. David. A Guide Book of Mercury Dimes, Standing Liberty Quarters, and Liberty Walking Half Dollars. Whitman Publishing, 2015. .Burdette, Roger. Renaissance of American Coinage: 1916-1921. Seneca Mills Press, 2005.Flynn, Kevin and Wexler, John. Authoratative Reference on Mercury Dimes. Kyle Vick, 2014.Lange, David, and Fivaz, Bill. Te Complete Guide to Mercury Dimes. DLRC Press, 1993. Sorry, I don’t have more to add. Imho, it’s difficult to tell because of the dark areas around the mm. They are nice coins .I have yet to see and hold one for myself To study. Hope this helps.
Ty. I did check these prior to making post, didn't see it there I don't think but thought maybe this could be one not listed there yet
Thanks for checking it out! Would you mind showing me where on the coin you see the possible clash marks? Just trying to learn as much as I can & see what others see (Btw I did reference http://www.error-ref.com/clash-marks/ to read about this again more after your post)
