'Increasingly rare' unpublished Lincoln letter goes for $85,000

A recently discovered letter written by President Abraham Lincoln that offers a glimpse into his thinking during the early part of the Civil War sold this week in Pennsylvania for $85,000, according to an autograph dealer. The previously unpublished letter had been in the same private collection for at least a century before it was acquired earlier this year, said Nathan Raab, the principal of the Raab Collection, which buys and sells historical autographs, documents and signed letters. -- Article
