Does anyone remember the 2004 Florida quarter that was attached to the New Horizons space probe to Pluto, and beyond? Of course, we will never get it back, though. Ha, ha!
Actually there were two quarters on opposite sides of the probe to balance each other out. The second quarter was a Maryland. It was there to represent the NASA Goddard center which is in MD.
