I think the casinos will continue to use colored caps for various strikes. They may also take some of the existing dies and modify them, resulting in a new strike. It is a minor operation to modify as existing die and many of the strikes have plenty of room to enhance the image. That will keep the play going and the % of profit coming in. There doesn't seem to be as many collectors collecting the colored strikes but that is the only way to get that strike image. I have several reds from Slots-A-Fun that I would like to sell. $80 each....free shipping
