This listing is for the single old school challenge coin pictured. This is a version from the early 1990s with no enameling and with the engraving panel on the reverse, from back when the only challenge coin you had as a rank and file soldier was your own from your current assigned unit, identified to you by your name, initials, or nickname engraved on it and you carried it for challenges.
