I also collect US players cards but only if issued to me personally - when we come to Vegas I always have one day where my wife and daughter chill out by the pool and I have a drive to as many casinos as I can get to off-strip to pick up new cards - a fun trip, never quite know if it is going to be a new issue or not (although usually is) and costs nothing but the gas in the car!

And of course I stop at one or two of the collectibles stores and pick up some chips as well (that is a more expensive stop )

The fun is in the chase!
