The Apollo 11 crew used hundreds of autographs as life insurance
Neil Armstrong and the Apollo 11 crew faced the real chance that they wouldn't return from the moon safely, leaving their families without financial support. Due to the extreme danger that they were about to face, they couldn't take out life insurance policies. So instead, they signed hundreds of autographs, which their families would have been able to sell if they didn't make it home.
Luckily, those life insurance autographs weren't needed. They do, however, show up in space memorabilia auctions today, selling for as much as $30,000.
