What causes you the most frustration as a card collector?- Being so close but yet so far......There were (4) D355s that were walked into a coin store a few years ago. The owner had no idea what he had nor did the coin shop owner. They didn't make a deal, the guy left and was never to be seen again. I bugged the coin shop owner for about a yr after that and he said the guy never came back nor did he have contact info. I still have scans of the cards though
