I've read in some of the various slot machine books that some machines reflect this payout range because the thickness of different coins in the payout tubes could cause a variation in the payout. So I would think the Operator would request this type of award card from the manufacturer, or make those cards themselves, to reflect that variation. Also, I think the silver coins of that time period (10, 25 and 50 cent) would wear more than the copper-nickel coins that started to be issued in 1965.
