Founded in 1973, the Gold Coast Treasure Club is a not-for-profit group that hunts coins, jewelry, relics, and artifacts on land and in shallow water. Guests are welcome; there is no December meeting listed, and the club holds a holiday party in December. Sources: http://goldcoasttreasureclub.com/ and http://goldcoasttreasureclub.com/directions.htm
