Estimate  $1,000 - 1,500. Mail from Confederate soldiers in Union prisons to the South generally bore the U.S. 3¢ stamp of 1861. However, Confederate postage was also required to be paid. This was accomplished by placing a Confederate stamp on the envelope when the prisoner had access to such postage. If the envelope lacked the proper Confederate postage, it was forwarded within the Confederacy with a postage "Due 10" marking. Because most Southern prisoners could not obtain Confederate stamps, covers with both Union and Confederate stamps are quite scarce. Lieutenant William A. Smith, was captured at Spotsylvania Court House, Virginia, on May 12, 1864, he was first taken to Point Lookout Prison and then transferred to Fort Delaware Prison on June 23, 1864. Lieutenant Smith survived his captivity and was released from prison on June 16, 1865. $0 (Image)
