Norm - This was tossed around sometime back by the casino's that had strike programs and the thought was gaming might not approve of it and the machines would have to be changed to .50 machines or the hold percentage on the .25 machines would have to double and that doubling would be at or over what the gaming board allows, and it was also thought they wouldn't get as much play on a machine that took $1.50 per play.
With the price of silver still going up it going to make matters worse.
