What University Archives does

University Archives (legally University Stamp Company, Inc.) is a privately held online auction house founded in 1978 by John Reznikoff and headquartered in Wilton, Connecticut. The company specializes in rare autographs, manuscripts, historical documents, rare books, photographs, and memorabilia, conducting monthly online-only auctions distributed through its own website, Invaluable.com, AuctionZip.com, LiveAuctioneers.com, and native iOS/Android mobile applications to bidders in over 60 countries. Beyond auctions, the company operates a portfolio of adjacent services including authentication (led by Reznikoff as expert witness for the U.S. Justice Department and FBI), USPAP-compliant appraisal services recommended by Christie's and Sotheby's, private treaty sales, consignment services offering up to $1M in cash advances, and in-house insured shipping via FedEx with Berkley Asset Protection coverage.

Revenue is generated primarily through a transaction-based model: a 25% buyer's premium on hammer prices via the company website and two third-party platforms, with a higher 28% premium for LiveAuctioneers bids. Consignors receive cash advances up to 100% of estimated value plus free inbound shipping, authentication, and insurance. Marquee engagements include the 40-million piece Richard Nixon archive appraisal for the U.S. Justice Department, multi-decade relationships with the George Patton and Malcolm Forbes estates, and recurring appearances by the founder on Netflix's 'King of Collectibles' series. Customer segments span wealthy collectors and investors, estate sellers, legal and law enforcement agencies, and museums/institutions.

The company's competitive position is anchored by Reznikoff's 45-year industry tenure and $250M+ in career transactions, the proprietary VSC4plus Video Spectral Comparator (the only such device among individual dealers), dual authenticator status with PSA/DNA and JSA, and recognition including IADA Person of the Year and UACC Autograph Dealer of the Year. The firm employs approximately 13 key personnel across auction direction, consignment, authentication, finance, and shipping functions, operating from a 6,000-square-foot facility in Fairfield County, Connecticut.
