Jill,

I got my $1 Harrah's from a co-worker. He ran the Mizpah when my company owned it. He claims it was a sample that was given to him. You would need to check the dates that IGT owned the Mizpah to determine when he would have recieved the chip.

Just out of curiousity, how many $25's and $1's came out of the Caro collection?
