I dont know the history behind the 2 dollar tokens, but, I have the wwhole set of 7 of them From Harrahs Reno on ebay and a set for trade. They are the wwonders of the workd set and really quite sharp looking..I didnt think brass could be nearly as shiny as silver was. They are ther size of the 7 dollar silver strike..Thats about as much as I know about them.
