Even casinos like Peppermill in Reno that have been tokenless for quite a while continue to offer machines that pay out in Silver Strikes. They are really premiums-- not tokens at all, although most are marked "gaming token". I look at them like the pocket knife or kewpie doll you can win with the "claw machine" in the arcade.

The casinos will continue to offer them as long as they can sell a cheap token for $10. They will likely demonitize them when discouraged "investors" start turning them back in in quantity.
