3.35% of my Nevada chips have come directly from casinos.

I've purchased chips from 636 different sellers. My favorites have been Spragg (13.00%), Clem (10.70%), Weintraub (9.60%), Saito (7.06%), and Hughes (5.42%), so about 46% of my collection has come from 5 guys.

P.S. - I keep pretty good records.
