Hi Gene, most casino's only put out sets of four or five $10.00 strikes each year. When I go to play it does not take to long for me to get the strikes I need to complete a set for my collection. But I still enjoy playing the strike machines and if you have the $200 strikes, I'll just have to keep playing until I have an extra 20 to trade for that $200 strike. I'm not a chip collector (not yet) but I believe they just buy them (chips) at the cage (no fun) I have to play a strike machine to get one, and I do enjoy the excitement of the strikes droping into the hopper (now thats fun)
