Kathleen Duncan

Owner - CEO - Trading

Kathleen co-founded Pinnacle in 1992. Her focus is finding intrinsically rare coins at fair prices and assisting collectors with building the numismatic portolios of their dreams. Through a long-term process of honesty and integrity, she has earned one of the industry’s most stellar reputations as well as the loyalty of her clientele.

When not managing the company, she and Dan are busy raising their three children. Kathleen also enjoys taking advantage of the beautiful Pacific Northwest by snow skiing in the winter and kayaking in the summer.



Dan Duncan

Owner - President - Trading

Dan has been involved with numismatics since 1987. From humble beginnings in the back of a coin shop, to the president of one of the nation’s leading wholesale rare coin firms, Dan has always prided himself on promoting the hobby. A collector himself, his years at U.S. Coins educated him in all levels of the numismatic community. Dan can be seen buying six figure coins one night, and passing out pennies to Scouts the next. A life member of the ANA, his dedication to the hobby is centered on education for both young and old alike.
