John's right. But buy 100 current $1 chips each year for the next 10 years. You can sell current $1 chips, as soon as they are released, for 3x-5x face value and see a nice return. The only problem with easy money is that it takes work. You have to find the right casino, buy the chips the week they're introduced, and advertise to local buyers. Here are some good examples of current $1 chips on eBay -- all well above your 10% return requirements:
