Okay, refresh my memory here. So I guess you submitted the coin with the fingerprint on it? If so, did you "try" to remove it with acetone before submitting? Ref, @Insider and @GDJMSP conversation.
I didn't. I've tried that on coins before and can't seem to make it work. Kinda scares the crap out of me. It looks like they graded it with the fingerprint.
Yes, I agree. Don't touch or clean any coins unless you are confident you know what you're doing. Like the guys above say, if it's an old fingerprint it's probably etched into the coin. Still looks like a nice coin though! On a side note: How many coins did you submit and how long did it take you to get them back?
