Like collecting anything....the fewer there are, makes the ones we have worth more. I don't collect for the silver content, I collect to keep the history of Vegas and other casinos alive. To me the strikes tell stories of what use to be. I'm from a small town in the midwest and knew nothing about Vegas or any other casino until I started collecting. Just look at how many casino's don't exist anymore. Not just strikes but any tokens/chips. But that's just me.
