Didn't have to say where it was placed. I was there in the 80's when the first arcade opened up across the street from my house. I watched them test it with the door opened. There was a latch that the coin hits when it goes through to give credit for the quarter. The latch closes behind the coin so you couldn't pull it back. Which means anyone who says they were able to use strings to get their quarter back was LYING.
Not quite accurate. Base upon my experiences, yes there is something in there that if you put it too deep, it will trap your coin. Coining for credits is like sex. You got to know where her zone is to get that credit and when you hit it, you keep it there and wiggle your coin so you can get more credits. If you lose your quarter, it is still good cuz you gained lots of credits. Sometimes you can get your credits and get your coin back by pushing the return button inward. If it is an arcade like no one is watching it like some laundry mat, I would just tape the string onto the arcade machine itself but if it is at a place that has employees present, I would get credit the most sneakiest ways and try to get my quarter back for the win or just loose quarter.
So for theking sake, it DEPENDS
