The listing, Japanese Daigaku Pachinko Token Coin has ended.
Found this in the basement of a foreclosed or abandoned house I was cleaning one summer and didn't know what it was but it looked like a real silver coin. It's very heavy and the size of an American quarter and the detail is very nice. (I will try to get a photo of it on here as soon as I can, my camera is not operating at the moment). It is the same on both sides, says daigaku pachinko on both sides and has Oriental writing. It has a raised edge. My research found out it is actually a token from a gaming parlor in Japan, daigaku means "university" and pachinko means machine like slot or pinball gaming machine. Here is the entry from Wikipedia:
Pachinko is a Japanese gaming device. A pachinko machine resembles a vertical pinball machine, but has no flippers and uses a large number of small balls. The player fires balls into the machine, which then cascade down through a dense forest of pins. If the balls go into certain locations, sequences of events are triggered that result in more balls being released;[1] these balls can then be exchanged for prizes. Pachinko machines were originally strictly mechanical, but modern ones have incorporated extensive electronics, becoming similar to video slot machines.
The machines are widespread in establishments called parlors, which feature a number of slot machines; hence, they operate and look similar to casinos. Modern pachinko machines are highly customizable, keeping enthusiasts continuously entertained. Because gambling for cash is illegal in Japan, balls won cannot be exchanged directly for cash in the parlor; instead the balls are exchanged for tokens, which are then taken outside and exchanged for cash at a place nominally separate from the parlor and possibly run by organized crime.

Good luck to all bidders!
