I would like to lend my opinion, I 1st would say that SuperDave is one of the resident
Morgan silver dollar experts,Believe me ( in my opinion )! I too believe this coin has a very UN-natural finish appearance, I would agree it has been altered at sometime. I also would say there is no natural luster left!
I would also say this coin, in the condition I see it in is in no way a MS condition, I have also been collecting these coins for many, many years and have come to know what to expect from a "natural luster" finish on a Morgan. I would suggest you look at this coin under a microscope and you will see a complete different picture, compared to a known MS Morgan.
If my memory is correct, this variety has an EDS and an LDS, This is, IMO, a LDS example, with the EDS example being of more value. This is just my opinion......
