is it MD? Can't tell, but it looked like normal master die doubling.

It is normal Master Die Doubling Jason. The coin look's like a good deal, but when you look closer........ :)

Yea I know its MDD but WHY would someone want this coin at all? Or have it slabbed for that matter?

[jcuve]

Total waste of a slab, the money spent on the slab and of course the goofball who just purchased it...
