Among the most intriguing auctions this summer at Heritage Auctions, the world’s leading collectibles auctioneer, are The Armstrong Family Collection™ Part III, which will be in Heritage’s Space Exploration Auction July 16-18 and the Nature & Science Auction July 20. Both events will be held in Dallas, Texas.

First moonwalker Neil Armstrong’s personal collection and archive will be offered in the Space Exploration Auction. Select highlights of the collection include Armstrong’s One and Only Lunar Module-Flown MS67 NGC 14K Gold Robbins Medal, Armstrong’s copy of the preliminary Apollo 11 flight plan and an internal NASA memo discussing what Armstrong should say once he stepped on the moon.

The Nature & Science auction will feature an unparalleled assortment of Lunar and Martian meteorites, including some of the largest and rarest known examples. One is a massive specimen measuring 7-1/2 inches long and weighing 6.4 pounds that comes from the end piece of a lunar meteorite. One of the most spectacular lots in the sale will be a pair of Model 1911 pistols made almost exclusively from the Muonionalusta meteorite, one of the oldest known meteorites on earth.

The Nature & Science auction also will feature a breathtaking assortment of gold specimens, some of which are massive – one even tips the scales at about more than 87 ounces. Included in the group are Crystallized Gold from California, Gold Nuggets from Australia and even a gorgeous Nugget from Cuba.
