The Black Californians were not American Indians but people identical to Africans in race and features. In fact they looked like Africans and somewhat like Melanesians. The history of the Black Californians may appear to be shrowded in mystry, however that is merely due to the attempt to keep their history obscure by not mentioning that the original people of California included Blacks as well as American Indians who existed there for thousands of years before Columbus.http://www.beforebc.de/Related.Subjects/Queen.Califia.and.California/Califia09.htm

The obverse of the coin depicts the Queen in profile, modeled after fellow graduate student and theatre major Marsha Stephanie Blake. The reverse of the coin has a small armada of ships, a griffin, which the women of California used in their wars against men, and an actual map of the State of California from the late 17th Century depicting it as an island. There are many famous maps from the 16th Century up to the 18th Century that clearly - yet erroneously - show California as an island. The story even told of the only metal the women had to work with was gold.
