You are buying a challenge coin from the US Army's Petroleum Systems Technician Warrant Officers.  Measures about 2".  Carry wear to both sides.  Email questions and buy with confidence.  If you are going to buy more than one coin, please make use of the Ebay Shopping Cart so you will get a combined shipping discount or wait to pay so I can combine shipping.  Sometimes coins don't like my flash, so I include another shot without a flash to help you read/see details.  I make every effort to get all my coins from the private collections of Soldiers, Sailors, Airmen and Marines.  I don't buy from overseas or direct from manufacturers.  These are real coins!  Thanks for looking and be sure to check out my other great store and auction items!
