Thought I would post a couple of pictures to see what you think. I'm guessing this is MD. It only appears in three areas of the coin. Everything else seems normal.
Photo #1 - Clear SD/MD/Flat-Field Doubling (whatever one wishes to call it) of this type is quite common on many dates of the LMC (both Copper and Zinc). Photo #2 - Maybe it is just my eyes... but it looks like nothing more than a dent on the "D". Photo #3 - It is hard to tell for sure from the image, but it appears to be just another form of SD. Most definitely not DD.
