A National Aeronautics and Space Administration name tag coated with lunar dust that was worn by an astronaut who walked on the moon sold at auction for $310,500.
The 6-by-12-inch cloth keepsake was cut from an insulated jacket worn by an astronaut, the late James Irwin, during the 1971 flight of Apollo 15. The lunar dust -- which created a dark gray tint around the raised edges of the tag -- became embedded into the tag during Irwin's three separate moon walks.
Irwin cut his tag, bearing a NASA emblem, off his jacket before it and other equipment were left on the moon to lighten the load on the spacecraft's return.
The item, which Christie's auction house sold Saturday on behalf of Irwin's estate, went for three times its presale estimate and was the highest-selling lot in a sale of nearly 300 space-related items.
A spacesuit worn by Neil Armstrong during training brought the second-highest price of the sale -- $178,500, more than twice its presale estimate.
