Robert A. Siegel Auction Galleries
America's premier stamp auction house, handling the finest philatelic properties since 1930.
Robert A. Siegel Auction Galleries is the most distinguished stamp auction house in the United States, with a history that dates back to 1930 when Robert A. Siegel launched his first mail sale from Kansas City, Missouri. Over the decades, the firm has grown into the largest and most respected philatelic auction house in America, known for handling the most important stamp collections ever assembled and for achieving consistently strong prices that reflect the firm's deep expertise and carefully cultivated buyer base.
The founding story of Siegel Auction Galleries is the story of one man's passion for philately growing into an institution. Robert A. Siegel (1913-1993) began his auction career with a modest mail sale of U.S. wholesale lots that closed on May 28, 1931. By 1934, he had moved his business to New York City, where he conducted his first public auction on October 17, 1934, from Room 605 at 116 Nassau Street, then the heart of New York's philatelic trade. Over his lifetime, Siegel conducted 756 philatelic auctions, establishing a standard of excellence in cataloging and presentation that the firm maintains to this day.
The firm's rise to prominence accelerated in the 1960s and 1970s. In 1964, Siegel held his first Rarity Sale, a concept that would become the firm's signature event, offering the finest and most valuable stamps available in any given season. In 1970, the firm achieved international recognition when it auctioned the British Guiana One-Cent Magenta, widely considered the world's rarest stamp, at a glamorous event at the Waldorf-Astoria Hotel on Park Avenue. The Siegel firm's handling of this legendary item cemented its position as the auction house of choice for the world's most important philatelic properties.
Today, Robert A. Siegel Auction Galleries is headquartered in midtown Manhattan and conducts approximately eight auctions per year. The firm's annual sales consistently rank among the highest in the global philatelic auction market, with recent annual totals reaching $36 million and beyond. Their expertise covers virtually every area of United States philately, from colonial and pre-stamp postal history through modern commemoratives and back-of-the-book material. The firm also handles world stamps, postal history, autographs, and ephemera, though American philately remains the core of their business.
The Siegel Rarity Sales remain the most anticipated events on the American philatelic calendar. These carefully curated auctions bring together the finest stamps, covers, and postal history available, attracting bidders from around the world. The firm's client list includes many of the most accomplished stamp collectors alive today, as well as major institutional buyers and investors who recognize the long-term value of rare philatelic material.
Siegel's cataloging is considered the gold standard in the industry. Each lot description is meticulously researched and written, providing detailed information about printing varieties, plate positions, census data, and provenance. The firm's catalogs serve as important reference works, documenting the history and pedigree of the most significant stamps to pass through the market. The firm also maintains the Siegel Census, a comprehensive database of important stamps and their auction history, which is an invaluable resource for collectors and researchers.
The bidding process at Siegel is designed to be accessible and transparent. Bidders can participate in person at the firm's Manhattan saleroom, by telephone, by mail or fax bid, or through the firm's online bidding platform. Registration is straightforward, and the firm's staff is available to assist new bidders with the process. All lots are available for viewing by appointment before each sale, and the firm's specialists are happy to provide condition reports and opinions on individual items.
The firm charges a buyer's premium on all lots sold, in line with industry standards. Seller commissions are negotiated individually based on the value, quality, and marketability of the material being consigned. Siegel's track record of achieving premium prices means that net results for consignors are typically among the best in the industry. The firm also offers outright purchase for collections where the seller prefers immediate payment.
Beyond the auction room, Siegel operates an active private treaty department, handling confidential sales of important philatelic material for clients who prefer discretion. The firm also provides appraisal services for insurance, estate, and donation purposes, drawing on their unrivaled knowledge of the American stamp market.
The firm has handled many of the most important collections in American philately, including the Josiah K. Lilly Collection, the Clifford C. Cole Jr. Collection, the Honolulu Advertiser Hawaii property, and the holdings of Clarence Brazer and Saul Newbury. Each of these sales represented a landmark event in the philatelic market, and the Siegel catalogs documenting them remain essential reference works.
Frequently asked questions about Siegel include how to obtain an auction estimate for a stamp collection (contact the firm by phone or through their website for a free assessment), whether they handle foreign stamps (yes, though their primary strength is American material), and how to view lots before a sale (by appointment at their Manhattan gallery).
