NGC AU-55 Mexico 1755-Mm Pillar Coin

This coin was purchased from a seller in Mexico on ebay.And when it arrives to me I found it a nice one with oringinal luster,although it had a long ago cleaned,I decieded to send it to NGC.Fortunatly NGC did not mark it as Cleaned which not gradable,it was certificated as AU55.This is my second NGC AU condition pillar coin.I have other 10 portrait pillar slabbed by NGC with about uncirculate condition,but in my experience in collecting 8r, the chance to get a AU pillar is as tenth as get a portrait pillar. So I like this very much although it is not a quite rare coin.
