That is the way YOU see it. Several posters, including myself see a slight rub. What if they were right the first time, and it gets resubmitted, and they conclude again that it is damaged? Risk vs reward.
I'm not gonna resubmit b/c the difference b/t 62 and 63 is only about $500.I have handled enough gold pieces to know what I am talking about.
I'll submit that the OP proved this statement invalid wit his experiment. Reliable, by definition, would mean that this coin would have come back with the same grade both times. This happens all the time. They are about as reliable as a chocolate fireman.
So have I-- it is a good looking coin, but I think it has been damaged. You were fortunate to get it graded.
If this is a damage coin then there are a lot of damaged coin in slabs. If you held this coin in your hand I'm sure you will call it a 63... I once cracked a $22K PR64 gold piece out of a slab and it came back PR65.
So, TPGs do make mistakes. I think it was a "thumbed or lightly polished coin." The original call was the right one.
Who knows if its surfaces were altered or not, but I'm still curious why they gave it the code 95 for a scratch. Is the lighting in the pictures hiding something? It appears to be a pretty coin regardless.
The coin appears very undamaged. Very few nicks and scratches which would lower the grade....looks from the photo the luster is a hair off and possibly not the best strike on the obverse
