"I do put them in plastic sheets (9 per page) to take to shows as I don't want to carry a box of 500 cards and run the risk of dropping them. "

Here is a new question. I have one book of traders that has one card of each in it. I kept this aside for when we did round robins. It was easy to see what I had. All my extras are thrown in a box. Im thinking when I go to the convention and bring my cards should I just throw all the dupes in one box or some how sort them out. What does everyone else do? Barry
