Type PMD. Looks like someone either popped the leg off that R or it took a lucky hit. What do you mean "type" Mrisa? Is there something besides the R that you are asking about or see???
Well according to what I've read there are three "types" of this DDO coin. John Wexler recorded these DDO-002 DDO-003 and DDO-009 so i was wondering if this was by chance one of these above and if so which type (1,2 or 3).
The "R" on yours looks like it might be the result of a grease-filled die or, possibly, damage as others have suggested. In Wexler's image of the 002, you can see that the vertical thickness is greater. The 003 shows a vertical line of separation in each letter. The date on yours has seen a lot of circulation wear and looks nothing like Wexler's 009. Chris
