Take what it would cost to buy the cut, add in the cost to have Leaf turn it into a card, and that's your value, because you could do the same thing yourself. You might have to wait until the next year to do so, since I think they have a limit on 1 of each signature or signature combo per year to maintain the "1 of 1" status, but it's not like this is the only Ruth/Gehrig cut that will find its way into a card ever. Based on what the others are saying, if you can get the cut for $7k, paying another $7k to have it in a card seems like a very high premium. Personally, I'd rather have two Ruth/Gehrig cuts than 1 in a card/slab
