Gives me a thought I'd like to try on my own machine I've set up to take any coin larger than a dime, and smaller than a half dollar.

Wondering if I could fish a small strand of copper wire down through it to hit the switch? I think I might try it. I like a challenge. Will report back if I'm successful. Then you'll find me at the local arcade....when I find one.

Those coin doors are designed pretty well at least on dmd games. That would be extremely hard to shove something into the coin slot and fish it down in such a way that you were able flip the switch multiple times..

I agree. Install bill validators and remove coin mech. I'd try different brand coin mechs.
