Just find the one that looks like yours and click the link to find out why parts are hard to get!
Note that if you are looking for parts:
Coin mechanisms are essentially universal
Common parts are generally standard within a manufacturer
A reject button from a CC over/under door will fit the other doors
(TODO: Insert picture of Coinco coin door on early Atari games.) Atari went to Coinco coin doors on games like Asteroids Deluxe, Centipede, and Tempest. (TODO: Insert picture of over/under door, both CoincoandCoin Controls flavors, starting around 1982.) Atari used Coinco and Coin Controls over/under doors arbitrarily from after around 1982.
Note that Atari’s manuals are excellent. You may be able to figure out which type of coin door you have by looking in the manual.
Data East sold their pinball version to Sega, who continued to use these doors.
(Insert picture of 1962 door.)
Midway (and Bally/Midway)
Sega used Coin Controls coin doors.
Classic Stern used the same doors as Chicago Coin.
2023 Spike door. This is reportedly a cost-reduced version of the previous door, although I haven’t verified this. Stern makes “compatible” changes to the same part without changing the part number. It is possible this is the same door with no, or some, cost reductions. However, the “Stern pinball” logo on the coin inserts is a nice touch. Part number is 501-5018-173, with a SPIKE (pinball system) compatible harness.
