In March 2011, a Maryland court with jurisdiction over Patricia Still's estate ruled that four of Still's works could be sold before they officially became part of the museum's collection. In November 2011, Sotheby's in New York sold the four works; "PH-351" (1940) for US$1.2 million, "1947-Y-No. 2" (1947) for US$31.4 million, "1949-A-No. 1" (1949) for US$61.7 million and "PH-1033" (1976) for US$19.6 million. The proceeds from the sales, US$114 million, went to the Clyfford Still Museum "to support its endowment and collection-related expenses." In the decade prior to the sale, only 11 of Still's works came up at auction. The Clyfford Still Museum opened on November 18, 2011.
