That was only an example. I remember when the older strike machines at some casinos were set so it was possible to win 2 or more on a single pull. I would expect the play would not be .75 cents. I would also expect the odds would be set a bit harder.
Back to my main thought was lets say the Plaza. If they kept the clads but added a red cap with a .999 silver would get the casino more play. More money.
Or not and folks will still play for a souvenir they can enjoy taking home and the collectors can also add them to their collections.
It's a fun hobby and the people I have met are cherished. Well most of them
