Feb. 20 (UPI) -- A letter by George Washington describing the sale of 90 slaves will be auctioned off Wednesday, the birthday of the United States' first president.
The two-page letter, written in 1774, two years before the Declaration of Independence was signed, will be among approximately 400 historical documents to be auctioned off by Cohasco, Inc., of Yonkers, N.Y.
The letter describes his sale of the Virginia estate of Col. George Mercer, a friend who served under Washington in the French and Indian War.
The letter was written by Washington on the day Thomas Paine arrived in America.
Washington ultimately ordered the emancipation of all of his slaves.
Chasco estimated the value of the Washington letter at $32,000 to $40,000. But bidding had risen to around $45,000 Sunday.
"What makes the letter historically significant is that Washington started life as a slave owner in his early teens and by about this time he began to realize that he had a conflict, an intellectual conflict," said Bob Snyder, vice president of Cohasco, to The Journal News. "On the one hand he was agitating for American independence and freedom. On the other hand he's surrounded by slaves."
The auction company also is selling an 1848 runaway slave poster offering a $250 reward for the capture and return of three black sisters named Maria, Susan and Harriet Johnson to their owner in Washington, D.C. They were caught and remained slaves until they were freed in 1864 when Abraham Lincoln's administration paid for their emancipation. This item's value is listed at $6,500 to $9,000.
Snyder said that the auction's end date was scheduled so it would fall near Presidents Day, Monday, a national holiday in the United States.
Cohasco was established 71 years ago and auctions historical documents, manuscripts, books, antique materials and collectibles.
