Record-Holding Autograph
The most expensive autograph in the world is a signed copy of the United States Constitution, sold at auction for over 43 million dollars. The document was signed by delegates including George Washington and Benjamin Franklin, and its rarity and historical significance drive the record price.
Why This Autograph Sells for So Much
Fewer than a dozen complete, signed copies of the Constitution survive, and only a handful have appeared at auction. Provenance, condition, and the association with the founding of the United States make each example exceptionally scarce. When a major copy changes hands, it often sets a new benchmark for autograph value.
Other High-Value Autographs
While the Constitution copy leads the market, other autographs regularly reach seven figures. Signed documents by Abraham Lincoln, Albert Einstein, and rare space-flown memorabilia attract deep-pocketed collectors. Prices depend on scarcity, historical importance, and verified chain of ownership.
