So i decided to message this guy, and heres what i said, "Hi, i recently won an auction for this peace dollar, and i assumed that the coin was an MS-65 coin. now that i looked at it, i see that the grading company is NNC. That grading company is unacceptable, and illegitimate for many coins, and im sure if you checked with more reputable companies, such as the NGC you would get a MUCH lower rating, especially after closely inspecting these pictures of the coin. An MS-65 coin is supposed to have few or NO scratches on the surface of the coin, and by seeing these pictures, it seems like this coin has a LOT of scratches. i contact you now, before i pay because i would like to not purchase this coin anymore. If that is fine with you, then i will just not pay and we will leave it at that, if not then i guess we will figure that out. I hope that you are understanding and that you can just relist it and sell it, and possibly get more out of the coin, thanks again for your time and patience."
hopefully he can accept this and i can get myself out of trouble...
