Features: Embellished in 24 karat gold. Motto "ENS CAUSA SUI" on one side means "A Cause Within Itself." Second motto "EX UNITAE VIRES" means "Out of Unity Comes Strength." Made in the USA. Description: Traditionally, American challenge coins began in the military as a token of the squadron or organization you belonged to, and they were also given out as recognition of bravery and service. Scholars are unsure if the practice began during WWI or WWII, but the practice does go back to ancient Rome when a soldiers was given an extra coin in his pay if he'd performed exceptionally well in battle. These coins are the same design as the ones used in the John Wick movies. An excellent gift for a courageous soul, or for someone who needs an extra bump of courage and support. This coin is made by Microtech Knives in the USA.
