Here's my favorite eBay auction so far this year.
It's a real $500 chip from the Desert Palace casino in Vegas for only $300. You know it's a real chip because the seller (0 feedback) brought it back from the tables in Vegas. All you have to do is return it to the Desert Palace where it's still in circulation.
