Going back a few years to when my friend Don Hallmark ran the Palms program, we looked at some costs.
Early Palms $200s contained what was in those days $130 of silver. By the time the cost of artwork, dies, setup, refinement, manufacture cost, capsules, velvet cases and delivery was figured in, cost was close to $200.
I suspect therefore that a $300 strike with $150+ of silver at current prices is costing a casino well over $200 to have made.
Figure in the cost of machine maintenance (much higher than average now no longer IGT supported) and other casino overheads. I suspect that no casino makes a profit on the strike program now in any case.
