..autographed chips.
Not sure I want to call them a catagory of our collectable catagories. Just a side line I started and could not quit.

Illegals? Not sure who has the biggest and have never even thought about it. I have over 1,600 ided illegals. I have 100's more put back to look into as possibly being able to get the ID's. They have been on hold since the Palms opened. I do not call them UFC's yet.
BTW, I have more than my share of UFC's. Doubtful they will ever be IDed.
I also have about 400 illegal traders that I never remember to trade. Most have been buried in storage. At chip shows it is easier to buy than waste a lot of time letting people go through boxes of traders. Most don't know if they have the chips in your boxes or not.
