The one on the left is what I found. The one on the right is listed as 1971S DDO + RPM. I found another site that has yet more images of one that has thinner doubling in the "in god we trust". What has me looking so hard is what appears to be a near perfect match of the "liberty" doubling. Here's that other site, I didn't want to post too many pictures. http://www.varietyvista.com/02b LC RPMs Vol 2/1971SRPM003.htm
