One of the last pieces of regular mail to cross the border from the Confederate States into the United States.This cover was mailed from Baton Rouge on June 5 and would normally have passed through Memphis, Tennessee. However, since the U.S. suspended service at that office on June 6, the letter was routed through Nashville and arrived at Louisville around June 10. It was sent north without penalty. The 10¢ C.S.A. postage paid the over-500 miles rate, and the sender affixed the 3¢ 1857 stamp to pay U.S. postage once the letter crossed the border. $0 (Image)
