The honor of the coin
Air Force Reserve Command, Command Chief, Chief Master Sgt. Ericka Kelly looks down at the coin she is about to present to Master Sgt. John Linafelter, 1st Sgt. with 73rd Airlift Squadron for his well executed planning of the Professional Development Seminar held July 7-8, 2016, Scott Air Force Base, Illinois. The challenge coin has a long military history with an uncertain origin. To receive a coin is an honor and signifies a token of appreciation. Typically coins are presented as a quick ceremonial handshake. (U.S. Air Force photo/Christopher Parr)
