Noob question here. What does "graded" mean for coins? I have a couple of redeemed 2013 1BTC coins (sorry if considered off-topic) that I would consider selling but not sure if they are "graded" or not.
If yours its redeemed, you cant get it graded, sorry. I have seen redeemed large value Casascius coins graded by Anacs. Obviously, you would not really want to spend the money to get a common redeemed coin graded, but maybe a rare one would interested someone who wanted the historic memento without the high cost of a 25BTC funded coin.
I believe there is a redeemed 25BTC coin on ebay at the moment. I will see if I can find the link.
EDIT - Here is the Coin in the holder:
