It is a Chipco... their Pro-tech line of coated metal gaming tokens. There is a $1 chip with exactly the same design.

Some collectors like these metal tokens (me included) and I'd suspect the token might bring a little more than its chip cousin.

Below are some more examples of the Pro-tech token from Chipco International's web site. I've only seen a couple of those in the picture. Would like to trade or buy any of those shown (even the car wash token)!
