I collect by topic so Harrah's isn't ruled out. I got pulled into this hobby with Halloween chips and now collect about 25 topics. I think I have a full set of every Halloween but there could be a few obscure ones that have gotten by me.

1. Halloween
2. Jesters/Jokers/Harlequins
3. Masks
4. Skulls/Skeletons
5. Anything Spooky
6. Snakes
