From Wikipedia: "In addition to the astronaut badge, which is worn on a military uniform, an astronaut pin is also issued to all NASA astronauts. It is a lapel pin, worn on civilian clothing. The pin is issued in two grades, silver and gold, with the silver pin awarded to candidates who have successfully completed astronaut training and the gold pin to astronauts who have flown in space. Astronaut candidates are given the silver pin but are required to purchase the gold pin at a cost of approximately $400. " (
