On July 9, 1776, the Manhattan printer John Holt gently edited the Declaration of Independence text and then published 500 copies.

Only four of the Holt Broadsides, as the documents came to be called, were known to survive until a few months ago, when a fifth surfaced in a private collection. The authenticated document and related papers, which belong to a descendant of some of early British settlers in eastern Long Island, will be auctioned on Nov. 11 at Blanchard’s Auction Service in Potsdam, N.Y.

The copy, which Blanchard’s estimates will sell for $500,000 to $1 million, was originally delivered to Colonel David Mulford, a regiment leader in East Hampton. Uriah Rogers, the soldier who brought the Holt page and other documents to the colonel, scrawled a note on the package that he had “made Bold to Open & Read them.” Mulford, who became known for battlefield heroics, died of smallpox in 1778.

Holt had edited Congress’s original text by adding a statement from New York politicians and changing some punctuation marks. Printings of his page have also survived at the New York Public Library; the Westchester County Archives in Elmsford, N.Y.; the Huntington Library, Art Collections, and Botanical Gardens in San Marino, Calif; and the Cincinnati Museum Center (which discovered a copy in its collection in 2015).
