Detroit casinos have them.

~Greektown $0.25
~MGM Grand $0.25
~Motor City $0.25

All three casinos have these 25 cent chips with both inserts and inlays. However...as the others have mentioned, there isnt a casino in the world that would let you walk out with that many. If you are deternined, you'll have to do it in steps. I think you'd be lucky to get 10 chips at a trip. So using the 10 chip harvested number, you could make 10 trips getting 10 nchips at a time and you'd have your 100 chips.
