This commemorative Challenger 7 Space Monument Project coin was owned by John Bickers, a Public Affairs representative for the McDonnell Company (later McDonnell Douglas), an aerospace company that held contracts with NASA throughout Project Mercury, the Gemini program, the Apollo program, and the Space Shuttle program. He obtained the coin in the course of that work.
This silver coin was minted in 1986 as a tribute to the seven people who died aboard the Space Shuttle Challenger when it was destroyed during launch on January 28, 1986.
During his tenure with McDonnell, Bickers compiled and edited Press Reference Books for the Gemini Space Missions and supported early Space Shuttle flights.
He donated this coin to the Museum in 2007.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
