I just looked at the one I have in my collection, and it's hard to read, but the front of it does say "Traded to the Bucks". Perhaps you can see it better on COMC.
However, there's a few on COMC like the one scanned here - they don't appear to have that stamp on the front. Should we have another entry for an ERR/COR, or a VAR? Or are my eyes just playing tricks on me?
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
