Claxton is an (L6) ordinary chondrite that fell in Evans County, Georgia, the evening of December 10th, 1984.
According to the Meteoritical Bulletin (MB 63):
A grapefruit sized stone, completely covered with thin black fusion crust, fell damaging a metal mail box and making a depression less than 30 cm (12 inches) in diameter in loose dirt. Two persons standing 36 m (39 yards) from where it landed and two others inside a mobile home about 20 m (65 feet) away reported a whistling sound followed by crash and a thud as the stone fell.
To date, 1,455 g (~ 3 lb) of the Claxton meteorite have been recovered.
In 2007, the mailbox struck by the Claxton meteorite was auctioned by Bonham's London with the following description:
While there have been hundreds of buildings and nearly two dozen cars struck by meteorites, there is only one mailbox known to have received an extraterrestrial special delivery.
