A collection of 30 pieces of Russell's art were sold for several million dollars at the Coeur d'Alene Art Auction (held in Reno, Nevada) in July 2014, setting new records for many pieces. Russell's "Trail of the Iron Horse" watercolor (depicting a group of horseback Native Americans contemplating railroad track) sold for $1.9 million, while "Dakota Chief" (which depicts a young Lakota chieftain on horseback) was auctioned for $1.1 million (almost double the last price it commanded). Even small pencil sketches sold for $25,000.
