This is a cool 1945D War Nickel RPM I found this weekend. I like finding RPMs on War Nickels because the mintmarks are so large that even the smallest RPM becomes dramatic.
I was not able to attribute which RPM # it is. There is a wide variety of information on the internet concerning Lincoln Cent RPMs, but if I'm looking for any other RPMs, I'm SOL. I do like the serifs on that one! Congrats on the find.
It is RPM 15. There is a great link on varietyvista.com to a free ebook on Jefferson Nickel RPMs. Great resource for attributing Jefferson RPMs.
Thanks for letting me know! I've been to James' site quite a few times now without ever noticing that.
