Ok you've been around long enough to know you should post full pics of both sides of your coin... Second I don't think I've ever heard of a DDMDO or DDMDR or any combination thereof. Your images are flat and shelf like!
Meow thought if some pointy parts of the lettering or numbering have a V like split, like in the V and E in the five shown here; was double die indicator. Is Meow mistaken about that? But either way, its a fairly good looking problem coin. Meow keeps ones like this, even if it may have no real value.
Well at my age and glasses you never no and I have been known to be wrong before but don't tell anybody. Lol Dave
Some people try to use this idea, and it does work if (1) It is a multi-squeeze hubbing year, and (2) the heights are the same or very close to being the same height. One high and one smeared , sharp parts or not, does not make a DD to me. But the single squeeze collectors might call it that. Jim
Thanks! With some research we might find proof in in a bottle! (Get it) lol. Thanks for sharing that's the first I've seen this!
