Chinese coins from six Pacific Northwest aboriginal sites are analyzed in terms of condition, dates, and identifying mint marks. The sites yielded 101 specimens. Two sites, Decker (35C02) and Mostul Grave (35CL3), contained Chinese coins that probably came into aboriginal use prior to 1830. Three sites, Trojan (35CO1), Gladstone Grave (undesignated collection in Clackamas County Historical Museum, Oregon City), and Sullivan’s Island (undesignated site excavated by the Smithsonian Institution in 1934), involved coins possibly in aboriginal use but problematic as to time and source of distribution. Coins from Bridgeport, Washington (surface collection), are probably traceable directly to post-1850 Chinese immigrant population. Most coins came from two rather distinct zones in China. One area centers on the northeastern provinces and Peking; the second centers on the southwestern province of Yunnan. Older coins (pre-1736 K’ang Hsi and Yung Cheng types) are from northern mints.
