My inexperience is showing again.

Hot Dog!!! I picked up a 10x loop today. Wow! the things you can see on a coin.

There in lies my problem. I have a a 1981 TII Ultra Cameo Proof set so naturally I wanted to take a good look at it since I have ideas of sending it in to be graded. As it tuns out, the coins are not mounted properly in the holder and the edges of the coins have been rubbing on the inside of the plastic case. Do I crack the case, remove the debris from the coins and put each coin in its on separate holder for safe keeping or do I leave the coins in the OGP and send it to NGC to grade and let them clean the debris off of the coins when they open it?

I told you this was going to be a learning journey!
