The Seth Kaller Distinction

“Sometimes, a document does more than capture a moment in history… Sometimes it is history…”

The Kaller family has long been known for building world-class collections of rare stamps and coins. When Seth held a block of four of the famous upside down airplane stamps in his hands, it was exciting, but by 1988, he chose to focus on historic documents. By 1990, he had already become the largest buyer in the field.

Documents that Seth has handled have since been exhibited at or acquired by The Smithsonian Institution, The National Constitution Center, Atlanta History Center,  The Gettysburg National Civil War Museum, the New York Stock Exchange, Mount Vernon, The University of Virginia, Rice University, Yale University, the Skirball Cultural Center, The Kennedy Space Center, The Lincoln Museum, and several Presidential Libraries and National Parks museums, and other notable institutions.

As an expert on important documents, Seth has been interviewed by The New York Times, Forbes Magazine and Lifestyles Magazine, as well as ABC, CBS, CNBC, FOX and Bloomberg Radio. He has published articles on the Declaration of Independence, Clement Moore’s authorship of The Night Before Christmas, and the Emancipation Proclamation and the Thirteenth Amendment. 

Seth has represented the Gilder Lehrman Collection since its inception in 1989. The GLC, now at the New-York Historical Society, is among the most important American document collections ever privately formed. Seth’s acquisitions for GLC include Benjamin Franklin’s signed copy of the U.S. Constitution, George Washington’s and Thomas Jefferson’s letters on the war, religion, slavery, and government, Abraham Lincoln’s “House Divided” Speech manuscript, and Robert E. Lee’s signed farewell order to his troops.

Since 1985, six copies of the Emancipation Proclamation with Lincoln’s original signature have been publicly offered — Seth kaller has handled them all.

Today, Seth works with both private collectors and institutional clients, including museums, libraries, universities and foundations. He is available for private consultations, appraisals and authentications.

Collecting History

Seth Kaller, Inc. invites you to experience the wonder of owning important historic documents. Our goal is to create a personal connection between you and your favorite historic event, figure, or idea. We specialize in finding rare items, with a particular focus on documents of significant content, which often are available for just a brief time and, once sold, may never come on the market again.

We hope that during your time at our website, you will get a sense of the wide variety of rare manuscripts and documents we are able to offer to our clients.

History You Can Own

Our Approach

We can handle and coordinate each aspect of the process, from locating single items to building an entire collection. Our clients include individual collectors to corporations, foundations and museums; what each shares is a passion for history.

Museum Quality, Private Ownership

Most people know that markets exist for Impressionist paintings, fine English antiques, or rare coins. However, the field of historic documents has long been quietly dominated by a select few: J.P. Morgan, Henry Huntington, Malcolm Forbes. This is changing as more collectors discover the satisfaction of a personal, unique connection with history.
