Any thoughts on this doubling? I usually see MD on one side of the number/image/letter, not on 2 or 3 sides. Same coin, same side
could be Longacre doubling.. http://www.numissociety.com/content.php?135-Longacre-Doubling-A-discussion
Longacre designed this coin too, and the "doubling" looks similar to the outlines you see on IHC legends.
