On January 19, 2006, New Horizons Spacecraft was launched to Planet Pluto with Maryland and Florida State Quarter coins with it! So this would be first time any commemorative coins ever will be going to place where no artificial objects has gone before. So to all numismatists and star trek fans; Boldly go where no commemorative coins has gone before!
It'll be the best part of three years before that begins any close in observations of the dwarf binary planet Pluto/Charon... anyway the "artificial object" Voyager is far beyond where this probe and it's dual purpose coin is.
