On May 30, Robert A. Siegel Auction Galleries will host a media event in advance of Siegel’s June 14-15 sale of William H. “Bill” Gross’ complete collection of classic-era United States stamps.

The press gathering will be held May 30 from noon to 4 p.m. Eastern Time at the Collectors Club, 58 W. 40th St., in New York City. Hors d’oeuvres, wine and champagne will be served from noon to 2 p.m.

Reporters desiring to attend the May 30 event should contact Siegel representative Alyssa Baumgardner at

Attendees may schedule interviews from noon to 4 p.m. with Siegel president Scott Trepel and Siegel International director Charles Shreve. For more than three decades, Shreve has served as Gross’ philatelic advisor.

In addition, there will be opportunities to view and photograph selected rarities in the Gross collection, including the famous 1868 1¢ Z grill (Scott 85A) and an iconic 1918 Jenny Invert airmail error (C3a).

An open house for the public will take place at the Collectors Club from 5 p.m. to 7 p.m., according to Siegel. Trepel and Shreve will give presentations about the collection at 6 p.m.

“The Gross collection has all of the obstacles to completeness, and then some,” Siegel said.

The 100 most valuable stamps in the collection will cross the Siegel auction block on the evening of June 14 at the Lotte New York Palace Hotel in Manhattan. The Collectors Club will host the sale of the rest of the collection the next day, June 15.

“This isn’t just a story about stamp collecting,” Siegel said. “This is a story about one man’s quest to achieve a goal [completeness] that is out of reach for almost all collectors.”

“Bill Gross diligently collected these tiny pieces of paper, placed them into a stamp album, and finished the job,” Siegel said.
