Coin Operated Collectors Association
The Coin Operated Collectors Association (COCA) is a society devoted to antique coin operated machines and related collectibles. Machines can include:
- Slot machines
- Trade stimulators
- Vending machines
- Arcade machines
It aims to improve knowledge of, and interest in, the collection of vintage coin operated machines and promote friendships between members.
Local meetings take place during weekends and two larger gatherings occur each year, in April and November.
There is also an annual convention, which includes an auction. The 2011 event will take place in Houston, Texas between September 16 and 18. The 2012 event will occur in Minneapolis-St Paul, Minnesota.
COCA publishes a magazine three times a year.
The website has details of upcoming meetings and events, as well as a “Did you know…” section.
