Again, heavily based on the year its from, but I bought a slot machine from 1982-1986 range (no exact year, just a range they were made) non-working for, I believe, $150. Same auction a fully working one from similar year range went for $400. I actually knew who sold that machine, I went looking at it 6 months prior. These both were Bally slot machines, mine was pulled from I think Tropicana, so I'm referencing Vegas slot machines.
