Tokens ftw. I used to use quarters, but oddly "for some reason" after friends and family would visit, id be missing more and more quarters. "forgot them in my pocket" etc etc...
Now i run 25mm(.984???) tokens. Sometimes they get forgotten in pockets too, but the difference is now they always eventually come back. (till somebody figures out they work at chuck e cheese lol)
They are slightly bigger than a quarter. Feels more like old school gaming to me. the 23.5s(.900?) just dont cut it.
The plus side to running 25mm is with some tinkering and filework, you can make almost any quarter mech take them.(no cost other than your time) same with coindoors. I wrote up a post about it several years ago, back in the day sort of speak. Unfortunately my picture server went rogue on me so the post is all messed up. Im waiting on admin here to let me post more than normal pics... In the meantime you can checkout the cleaned up version with all the pics at rotheblog..
I also run an old dead rowe change machine. The quarter hopper works fine with 25mm tokens. The computer in it is shot, but the 120vac hopper motors still work fine.
So i wired up the hopper motor one side to ac neutral, the hot side goes through a fuse to a pushbutton switch and then to the other terminal of the hopper motor. I wired the payout door open. So now all i do is hold down the switch and it spits out tokens. Perfect for what i wanted to do.
I think the change machine was like $50 or $75, tokens cost me not too much from noice like 40 or 50 per 1000 or something like that.., the rest was just time fiddling around to get everything right. TOTALLY WORTH IT.
