This set is from the Grand Opening commemorative Series 2003 from the Thunder Valley Casino in California .There are four of these tokens in a velvet covered box with the Thunder Valley Casino gold stamped on satin on the inside lid of the box . I don't know what the name for this type of picture is but it's like 3-D .Three of the tokens are the same and one has their logo in 3-D. All of the reverse sides are the same . I got these with a bunch of casino items and have two sets to sell if I can get a value on them . Each token is about the size of a silver strike and their in a celo. bag so they have not been touched .
