About Us

 

Stack’s Bowers Galleries conducts live, Internet and specialized auctions of rare U.S. and world coins and currency and ancient coins, as well as direct sales through retail and wholesale channels. The company’s 80-year legacy includes the cataloging and sale of many of the most valuable United States coin and currency collections to ever cross an auction block — The John J. Ford, Jr., The Louis E. Eliasberg, Sr. Collections, The Harry W. Bass, Jr. Collection, The Norweb Collection, The Cardinal and The Battle Born Collection — to name just a few. World coin and currency collections include The Louis E. Eliasberg, Sr. Collection of World Gold Coins, The Kroisos Collection, The Alicia and Sidney Belzberg Collection, The Wa She Wong Collection, The Guia Collection, The Thos. H. Law Collection, and The Robert O. Ebert Collection.

Topping off this amazing numismatic history is the inclusion of the world record for the highest price ever realized at auction for a rare coin, the 1794 Flowing Hair Silver Dollar graded Specimen-66 (PCGS) that realized over $10 million, part of their sale of the famed Cardinal Collection. The company is headquartered in Irvine, California, with offices in New York, Wolfeboro, Hong Kong, and Paris. Stack’s Bowers Galleries is an Official Auctioneer for several important numismatic conventions, including American Numismatic Association events, the New York International Numismatic Convention, the Professional Numismatists Guild New York Invitational, the Whitman Coin & Collectibles Spring, Summer and Winter Expos, and our April and August Hong Kong Auctions.
