The Riviera Holograms were sold at the Main cage for $10 apiece. They were NEVER in Silver Strike machines. The Riviera got rid of their strike machines in 1999. Holograms are NOT Silver Strikes. The most valuable Holograms from the Riviera are the first series they sold and only made 500 of each. I have sold a set of 5 for $250.00. They have also sold lately for less than that.
