Heritage Auctions is a privately owned company, with headquarters in Dallas, Texas and offices in New York, Beverly Hills, San Francisco, and Houston as well as locations in Germany, Switzerland, Holland and France.
Heritage combines both proxy and live Internet bidding with traditional floor auctions. In both 1999 and 2001, www.HeritageCoin.com, the predecessor to www.HA.com, was chosen by Forbes Magazine as one of the 250 best sites on the Internet. According to Internet traffic measurement site Compete.com, HA.com receives significantly more traffic than Sothebys.com and Christies.com combined. Heritage hosts separate website sections for each type of collectible they support and each lot's web listing contains third-party pricing and rarity data.
Auctions held through the firm include the Nicolas Cage comic book collection, which sold for $1.6 million in October 2002 as a part of the largest comic auction ever according to Guinness, the highest grossing numismatic auction (over $65.1 million at the 2007 Florida United Numismatists auction, not including currency), the highest grossing currency auction (over $14 million for the auction held at the Long Beach Coin and Collectibles Expo in September 2006), and the highest price for an action figure ($200,000 for Don Levine's original G.I. Joe prototype in July 2003).

Heritage Auctions was reported to suggest it had proof of the dinosaur's legal importation. Heritage and the Government of Mongolia later jointly announced their cooperation in investigating the origin and ownership of the dinosaur.
Heritage Auctions operates a charity auctions division for causes that have included the North Texas Food Bank and St. Francis Food Pantries and Shelters. Profits generated from Heritage Charity auctions are donated to charities selected by Heritage employees.
Antiques and memorabilia dealer Gary Hendershott has filed lawsuits against Heritage, including a May 2009 RICO (Racketeer Influenced and Corrupt Organizations) lawsuit alleging Heritage utilized shill bidding to increase prices, and failed to pay him commissions for auction sales he had facilitated for the firm. Heritage denied the claims, and the lawsuits were dismissed, without prejudice, by three different judges and sent to arbitration
In early September 2009 a similar RICO complaint was filed against Heritage by Chris Kortlander, a businessman from Montana who had once hired the firm. On September 25, 2009, all of Kortlander's claims were dismissed with prejudice.
On September 16, 2009, Heritage filed a motion asking for sanctions against Hendershott and his attorneys for misconduct.
On September 30, 2009, Heritage filed a lawsuit against Hendershott and his attorneys alleging defamation and civil extortion.
On April 7, 2010, U.S. District Judge Jorge A. Solis entered a permanent injunction ordering Hendershott and anyone acting on his behalf to remove from the Internet all previously published false, misleading and/or disparaging statements regarding Heritage and enjoining them in the future to desist from making or distributing such statements. The RICO lawsuit and all claims against Heritage were also dismissed with prejudice.
