Millions of years ago a meteorite slammed into Earth's surface in Africa. Prehistoric people used its iron to construct tools and weapons until the 1800's when it was discovered by western civilization. An American gun company mined the space iron and created a cosmic 1911 pistol set. This Big Bang Pistols are believed to be the only pair of meteorite-made 1911's. Naturally, they found their way to the only place they belong — an auction — and the starting bid is astronomically high. Learn about these cosmic beauties and more auction guns in this week's episode.
