Does anyone collect casino ash trays? We have a Caesars Palace with blue border and white people around the side, a Castaways - amber with green bottom, a Tropicana "Superstar Theatre" amber color. Does anyone know what they are worth or is anyone interested in buying them? We are taking 25 different ash trays to our club meeting tomorrow to sell, unless someone on the board is interested. The three listed above are duplicates. LMK Daryl
