If the obverse is a Native American on horseback, then this strike is a Colorado Generic Native American Series. Many of the casinos which were too small for their casino logo banded together to issue these. There are six in this series. Other Colorado Generic Series include Gunfighters (6), Lawmen (6), Explorers (6), Eastern Astrology (12), a similar Oriental series on which one side is all Chinese charaters (12), a Colorado SBtate seies (bird, flower, tree and seal) and agangster series (Bugsy Siegal, Al Capone, Lucky Luciano and Elliot Ness).
Some of these series, such as the Native American, were also issued by some of the Florida Cruise ships.
