Worthridge Auctions and Retail have a flown Apollo 15 cover as part of next sale opening for bids on Nov. 19. The lot is set to begin at $2,500.

This cover includes a certified letter/ LOA, notarized in 1985, stating that the cachet was indeed one that accompanied the Apollo 15 mission. It is signed by all three members of the crew (commander David R. Scott, lunar module pilot James B. Irwin, and command module pilot Alfred M. Worden).

Inside the envelope are two cards stating its number as 107 of 300.
