Re:Mitchell's spacesuit
A technician who's job was to clean Edgar Mitchell's spacesuit had collected a small amount (way back in 1971) of dust and didn't tell anybody , didn't sell and kept it religiously at home (spacenuts can understand that).
However, he passed away.
And his daughter knew about the moondust but didn't know about it's illegal possession when she tried to sell it, much to her chagrin.
