Rock Island Auction Company, the country’s largest firearms auction house, has been on both sides of the courtroom. The most consequential Rock Island Auction lawsuit was filed in 2012 by billionaire collector William Koch, who accused founder Patrick F. Hogan of selling him roughly $2 million in firearms at inflated prices and refusing promised refunds. The company has also sued a former consignor and rival auctioneer Heritage Auctions in a federal fraudulent-transfer case, and it publicly accused competitor James D. Julia of fabricating provenance without ever filing suit.
William Koch’s 2012 Suit Over Inflated Firearms Prices
In late March 2012, William Koch sued Rock Island Auction Company and Patrick F. Hogan in Palm Beach County Circuit Court in Florida. Koch alleged that Hogan had sold him about $2 million in firearms at “vastly inflated prices” through an absentee bidding arrangement rather than at reasonable market rates.1Palm Beach Daily News.

The centerpiece was a Colt D Walker model percussion revolver Koch bought in December 2006. A gun expert Koch hired examined the revolver and found the loading lever had been removed from the barrel and the resulting hole plugged. The suit alleged small dents had been placed around the hole to conceal the modification. Koch said Hogan had promised a full refund if any problems surfaced but later refused to honor that agreement. Koch also sought refunds on four other firearms bought in the same period, which the company allegedly declined.1Palm Beach Daily News. William Koch Sues Auction Company
The complaint included a breach of fiduciary duty claim and cited a Rock Island advertisement that reportedly boasted its sale prices were “283 percent higher” than competitors, which Koch’s lawyers framed as evidence of inflated pricing rather than superior value.1Palm Beach Daily News.

The available record does not show how the case ended. No public reporting on a verdict, settlement, or dismissal has surfaced. The suit fit a broader pattern for Koch, who by 2012 was pursuing multiple sellers of high-end collectibles he believed had defrauded him, including a separate wine fraud action that later produced a $12 million punitive damages verdict against tech entrepreneur Eric Greenberg in 2013.2CNBC.

Rock Island Auction v. Bob G. Dean Jr. and Heritage Auctions
More recently, Rock Island appeared as plaintiff. In 2023 the company filed suit in the Northern District of Texas against Bob G. Dean Jr. and Heritage Auctions after a consignment agreement with Dean collapsed. An American Arbitration Association arbitrator had already ruled in Rock Island’s favor on November 2, 2023, awarding the company $1,438,447.25 plus title and ownership of 11 consigned items.3CaseMine. Rock Island Auction Co. v. Bob G. Dean, Jr. and Heritage Auctions, Inc.
Rock Island petitioned the federal court to confirm the arbitration award and added claims under the Texas Uniform Fraudulent Transfers Act against Heritage. The company alleged Dean was dissipating assets by routing antique firearms and knives through a Heritage sale set for December 2023. Rock Island sought emergency relief, including a temporary restraining order and a writ of attachment to freeze the items. A magistrate judge recommended denying the emergency motion in December 2023, finding Rock Island had not sufficiently justified proceeding without notice to the other side.3CaseMine. Rock Island Auction Co. v. Bob G. Dean, Jr. and Heritage Auctions, Inc.
The case then stalled. Dean filed for bankruptcy, and in June 2024 the court administratively closed the matter under the automatic stay. Rock Island was ordered to file status reports every 60 days. By February 2025, Rock Island filed a stipulation of dismissal.4PACER Monitor. Rock Island Auction Company v. Dean, Jr.
Dean’s troubles extended beyond the consignment dispute. In October 2024 the U.S. Department of Justice announced that Dean and affiliated corporate entities had agreed to an $8.2 million consent judgment to resolve allegations that he violated the National Housing Act by siphoning funds from four FHA-insured nursing homes in Louisiana. Federal authorities alleged Dean funneled nursing home income into personal accounts and used the money to buy “antiques, firearms and cars,” among other personal items. The consent judgment did not include a determination of liability.5U.S. Department of Justice. Bob Dean Jr. and Affiliated Corporate Entities Agree to $8.2M Consent Judgment
The James D. Julia Provenance Dispute (No Lawsuit Filed)
One widely discussed episode never became a lawsuit but is often lumped in with Rock Island’s legal history. In October 2014, Rock Island published a detailed blog post alleging that rival James D. Julia Auctioneers was offering firearms with fabricated provenance claims, particularly items purportedly tied to the Battle of Little Bighorn and figures like Nicholas Black Elk and Charging Hawk.6Rock Island Auction Blog. A Note on Questionable Firearms
Rock Island presented side-by-side comparisons showing that several firearms in the Julia catalog had recently sold elsewhere with entirely different descriptions and at far lower prices. A Colt 1860 Army revolver Rock Island had sold in June 2013 for $2,000 appeared in Julia’s catalog with Little Bighorn provenance and an estimate of $8,000 to $12,000. A Southerner single-shot pistol Rock Island sold in early 2014 for $1,000 turned up in Julia’s catalog described as the weapon “used by Oglala Sioux warrior Chargin Hawk to kill George Armstrong Custer,” with an estimate of $25,000 to $40,000.6Rock Island Auction Blog.

According to Rock Island, Julia removed the questioned items from its online catalog after the discrepancies were publicized. Rock Island also said it had earlier rejected a single-action revolver with alleged ties to Cheyenne chief Two Moons for insufficient documentation, and that the same gun later sold at a Julia auction for a large sum. The exchange stayed on blogs and industry forums. No court filing between the two auction houses has been reported.
