Last night I was working on a pachinko machine and discovered the reason why the machine kept jamming.

Deep down inside the machine close to the payout motor was a small hearing aid battery. Looks like someone dropped it down one of the win pockets and it got pushed and rolled along for a ways until it got stuck causing a traffic jam.

Other things I've found inside machines....
Dimes
Pennys
BB the kind you shoot out of guns
Shotgun pellets (#8s I think)
Ball Bearings
Little red and white plastic balls (Lots of them)


These are just a few of the more interesting things.
Anybody discover other treasures inside a machine they are cleaning up.
