Military service men and women make big sacrifices for their country everyday, which is why it is nice to have a reminder of the importance of their job. This Air Force military challenge coin is a wonderful commemorative item.  Surrounding the symbol are the words "Air Force" and "United States of America." The coin is red, white, and blue, and it measures 1.75 by 1.75 inches. Military challenge coins are an excellent gift or memento for anyone who offers his or her life in service to our country.
