Impossible to give a grade opinion on those scans, because you can't see the coin enough to determine the devices and all.
Can you do close up photos of just the coin? Not the whole GSA slab. That way it will give us a better idea.
ok now I'm seeing some nicks on the bottom of Liberty's jaw. Can you take a clear, large picture of her head/cheek ?
alright then well I guess depending on the scuffs I'll just say MS-63 to MS-64. As an avid GSA collector and CC nut, nice coin
So my next question would be, would it be worth it to take it out of the GSA slab and send it to PCGS for grading, for just leave it alone?
Your not going to reap any benefit by removing the coin and submitting to NGC or PCGS. Leave it as is, is my suggestion. As for a grade, I'd call it a 62/63 at best from the photo's you provided.
DO.NOT.REMOVE.THAT.COIN.FROM.THAT.HOLDER if anything send it to NGC and it still grade it with a band around the GSA holder.
