Summary
Ken Griffin, founder and CEO of Citadel, solidified his position as a preeminent collector of rare American historical documents by acquiring two landmark Lincoln-signed artifacts for a combined $18.1 million. Griffin paid $13.7 million for a handwritten copy of the 13th Amendment to the U.S. Constitution and $4.4 million for a copy of the Emancipation Proclamation, establishing record prices for both documents.
The 13th Amendment acquisition represents the most significant milestone, as Griffin's purchase price of $13.7 million eclipses the previous auction record of $2.4 million for any copy of the amendment, representing more than a fivefold increase. The document consists of a single sheet of vellum signed by President Abraham Lincoln in 1865, the year the amendment was ratified and slavery was abolished throughout the United States. According to supplemental sources, only four copies of this handwritten version remain in private hands, establishing its rarity and historical weight.
Both acquisitions were completed through Sotheby's auction, with Griffin's purchases marking record-setting valuations in the market for Lincoln-related documents. The Emancipation Proclamation purchase at $4.4 million also achieved a record price for that particular document. These transactions reflect growing institutional and individual investor appetite for authenticated historical artifacts tied to foundational American political events, particularly those involving preservation of constitutional documents.
Griffin's dual acquisitions signal a broader institutional strategy in alternative asset collecting, where ultra-high-net-worth individuals and families deploy capital toward tangible, historically significant assets with limited supply and strong provenance. The purchases position Griffin among the most prominent private collectors of American constitutional history and align with patterns of alternative investment diversification among billionaire collectors and family offices seeking assets beyond traditional equities and real estate.
