Where is Bellman? He loves GSC. As for the coin, the photos are hiding something, it just looks hinky. I can't say what is wrong, only that something is wrong and that the coin has AU details.
That coin has an "oily" appearance. It is almost MS to me. I will say the impossible grade of AU-59 Details.
It's a dead coin, someone fooled around with the surface, took the life right out of it, turned it into a cadaver. I have IHC drink coasters that look more lively than that.
