I worked for Harrah's Reno in the early 1980's and those were used the the $5 slot machines - at that time I believe there was 2 Pace (Mechanical) and 2 Bally $5 machines. This was before high limit areas became a big $$ area for casinos. I wish that I actively collected back then. I remember one regular that would always play the Bally $5 machines otherwise I had really never seen anyone else play the $5 machines.
