I recently came across a set of $2.00 Edgewater, Laughlin tokens that depict the wonders of the world. I only found six in the set and thought that there were 7 Wonders. Could anyone list these tokens and an approx. value? Also, are these the same as the Harrah's tokens of the same name?

I don't collect tokens as a rule(except Silver Strikes, which I just started), so I haven't picked up any of the reference materials yet.

Thanks,
