I wonder how long ago he found these ?
“Numismatic Guaranty Co. (NGC), which certified the coins’ authenticity”
I am don’t know how long their backup is today, but last I checked it was 6-9 months
I am not sure how good they are cause I once bought as ms70 plat eagle but I would not even give it a 67.
I asked a couple LCS their opinion and they said the same thing.
but it could be a flaw in the plastic holder, so I guess I should send it for re-grading?
Yes, does PCGS still exist?
