Seth Kaller, Inc.

Seth Kaller is a leading expert in acquiring, authenticating, and appraising American historic documents and artifacts. Kaller has built museum-quality collections for individuals and institutions, as well as legacy collections for philanthropists to donate. 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.
