Dutch Country Auctions scheduled its 367th sale across three morning sessions in Wilmington, Delaware, from 10 to 12 November 2026. The auctioneer described the worldwide country and topical lots as the final offering of stock from retired dealer Stamp Smith. The sale also included a second specialised Ryukyu consignment with multiple varieties of an early issue.

The first day’s postal history included United States stampless, classic, military and naval covers and first-day covers with cachets by Dorothy Knapp and others. Among the overseas covers was an 1856 British mailing to the United States franked with multiple stamps, as well as German field post whose proceeds were earmarked for the American Philatelic Society. The U.S. section offered early issues, grills, Washington–Franklins and Zeppelin stamps, with certificates for many of the classic lots.

Beyond the U.S. and Ryukyu material, the auctioneer highlighted Japanese occupation of Brunei, specialised North Borneo, Newfoundland and certified classic Spanish stamps. The catalogue divided the sale into lots 1–565, 566–1135 and 1136–1712, with a 10 a.m. local start each day. Advance viewing was by appointment from 20 October.
