Welcome to C.O.C.A.
The official website of The Coin Operated Collectors Association & home to all things coin operated.
COCA will return to Phoenix Arizona for our annual convention. There have been big changes since we last visited in 2007. There are new collections to visit and the collectors that we visited in the past have grown their collections to new levels.
Every year at the November Chicagoland meeting, COCA enshrines one or more persons that have made significant contributions to the betterment of our club and/or the hobby of collecting coin operated machines.
