Yep, definitely MD
I agree with many of the comments that it appears post-mint. The color of the white metal appears inconsistent with that of exposed zinc....
Too bad I got to this thread so late as the answer was already given. I was thinking glue at first. It seems many a collector have been stumped...
I have no idea what that is, I agree with JC that it is probably just an old stain that has influenced oxidation or directly chemically reacted...
Rlm, you are correct, I shouldn't paraphrase eBay's policy. On that note I am including ta copy of rules pertaining to "Raw and uncertified coins"...
