Welcome to C.O.C.A.
The official website of The Coin Operated Collectors Association & home to all things coin operated.
Dennis Hartwig was inducted into the COCA Coin-Op Hall of Fame at our November 2019 club meeting. Dennis has offered up his help throughout the years to numerous coin-op collectors, often without asking for a dime. His knowledge of coin-operated machines goes well beyond any book of knowledge.
At the Fall Chicagoland Show, COCA sponsored a Parking Lot Coin-Op swap meet. It was held in the side parking lot of the Double Tree Hotel on Thursday morning. Despite the cold and snow, many members were there to buy and sell.
