Next week, the black and gold theater glasses Lincoln is believed to have used the night before his death are going back on the auction block, where experts think they could fetch as much as $700,000.

The glasses are part of a June 17 Sotheby’s auction in New York that will include pricey Civil War items such as a handwritten letter from Robert E. Lee discussing his resignation from the U.S. Army and a flag from the famous Confederate warship CSS Alabama.
