Not pins, but I do own the Chexx hockey game, Donkey Kong, and Mr. Do's Wild Ride I used to play at my local Chuck E. Cheese when I was a kid. I used to own the QBert, too, but I don't want to get into how it got sold. Long, sad story. I also used to have the Astron Belt(laserdisc game) from there, but that got left outside at my father's place and the cabinet practically disintegrated. I saved all the internals, though.
This was when CEC first sold out to Showbiz Pizza when CEC was going bankrupt. They closed the location by our house and auctioned off everything inside. I remember going with my mom and older brother and being amazed that she bought so many games! It was so cool seeing all those games come in through the front door!
