Topps Total sets had both the card number for the full set and an team set number, as jupiterhill alludes to. In the upper right corner, the top number is the card number in the set, and the number with the CHW- prefix is the team set. They are one and the same.
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.
