This Challenge Coin is from the 80th Aircraft Maintenance Unit "Headhunters" stationed out of Kunsun AFB, Republic of Korea. The coin has the unit's moto: Audentes Fortuna Juvat which is Latin that translates to "Fortune Favors the Bold". The size is 1-3/4" in diameter and weighs 1.4 ounces. This coin will make a great addition to any coin collection. I will combine shipping with other orders from my listings.
