I can see where the LL in DOLLAR looks like it could be DDR-001 http://varietyvista.com/12 Kennedy Halves/DDRs 1971-S.htm Here's some more pics of the Doubling: http://varietyvista.com/12 Kennedy Halves/DDR Detail Pages/1971SDDR001.htm I can't tell if your coin matches any of the other Doubled areas. It's much easier to do with the coin in hand. Please let us know if it matches the other areas. Thank you.
The coin photographed was verified by James Wiles on 10/25/2013 as the DDR-001, as such, there is very little doubt as to what it is. Another member wanted to verify what he has in his collection. The DDR-001, DDR-007 and DDR-009 have similarities. I would have sent a PM but unable to figure out how to send pictures in a PM, hence the reason for the post.
OK. I wouldn't have replied if you had mentioned that in your post. His email is jameswiles@sbcglobal.net
