But what you are seeing on the RPM-001 is the RPM area. You coin is just a normal die example with die wear and some MD on the west side of the mintmark. Check on your coin to see if other areas are showing the MD on the same side of the devices. Then you will see what this really is. Also, when taking images, it is helpful to show the full area in question around the mintmark. If this really was this die, the location of the mintmark would be the same as the one listed on V.V.
http://www.varietyvista.com/05%20JN...8DRPM001.htmNote the location of the mintmark on Variety Vista and see if the mintmark is in the exact same location. If you could take an image like the first one on the link, then I can make a side by side to show how the locations compare.
