QOD: Other than slot cards, what other casino "stuff" do you collect?

I collect:
Harrah's cards by location and back variation
Room keys (both casino and non-casino)
Phone cards (only have about 20)
TITOs (have over 300)
Matches
Handi-wipes (preferrably not generic)
Jackpot winner signs (have approx.115)
1 card from a deck of cards (I've accumulated about 3000 in the past year or so)
Ballpoint pens (have almost 600)
Bungee Cords - only those that have the little slot machine clip (currently have 42)
Chips and tokens (we're limiting ourselves to Colorado)

I also save, but don't make an all-out effort to collect:
Sugar packets
Coasters
Writing pads
Post cards
Miscellaneous paper things (i.e., Keno tickets, those things they put on the slot machines that dangle in your face, Do Not Disturb signs, almost anything with the casino name on it that's flat and will fit into a notebook)
