Civil War Proclamation For Sale: The document that Lincoln signed, which officially started the Civial War, is up for sale. It's value: nearly a million dollars. The privately owned, one-page document was signed by Lincoln on April 19, 1861, and authorized troops to block Southern ports, which, under international law, was an act of war. The document has been on exhibit for several years at various institutions, including the National Constitution Center and the Abraham Lincoln Presidential Museum and Library. But now the 150-year-old document is for sale. Interested buyers can make an offer through the Raab Collection's website. via CNN
