The most incredible stuff up for grabs, though, are the chunks of Mars like this unique shiny black number discovered in Morocco in 2011 and nicknamed Black Beauty. It's unusual in that it contains 10-30 times more chemically bound water than other Martian meteorites, and it didn't even tumble or invert as it descended through our atmosphere. Another standout feature? It's expected to fetch up to $100,000.
Don't let that all those zeroes scare you; some in the lot are up for grabs for as little as $600.
