Hi Everyone, Just found 1956 rpm. Also found 1993 rpm but can't find a similar example. Any help would be GREATTTT.
Also added a few new images of 1999 die clash in album.
The '56D is RPM-001 - a bold RPM and a nice find!
The '93D is not an RPM, rather a case of plate split doubling (split line doubling); the plating split along the struck seem and spread toward the rim. RPMs stop at 1989 as the Mint ceased punching the mintmark in to dies and in 1990 started adding them to the design.
