There is a way to send your coins in for grading and not have to pay the full grading fee for coins that wont grade!

Any time I have a coin that I am unsure if it will grade or come back in a BB I send it to NCS. If the coin is cleaned or damaged you can have NCS to return the coin to you and just charge the minimum NCS fee for looking at your coins. If you want it slabed anyway then NCS will slab the problem coin and list the problem on the holder. This will at least prove the piece to be genuine or not.
