Although I can not confirm this here is my guess. You are in Oklahoma according to above. Are you near Tinker AFB? Because my theory is the token is from Schofield Barracks in Hawaii. My research shows that Schofield Barracks is near Hickam AFB and at one time Wheeler Army Airfield.
From Wikipedia
Wheeler Army Airfield (IATA: HHI, ICAO: PHHI, FAA LID: HHI), also known as Wheeler Field and formerly as Wheeler Air Force Base, is a United States Army post located in the City & County of Honolulu and in the Wahiawa District of the Island of O'ahu, Hawaii.[4][5] It is a National Historic Landmark for its role in the 7 December 1941 Japanese attack on Pearl Harbor.[3]
[edit] OverviewWheeler AAF comprises approximately 1,389 acres (5.62 km2) of land adjacent to Schofield Barracks and home to a variety of Department of Defense activities including the Defense Information Systems Agency (DISA), the 169th Aircraft Control & Warning Squadron (169 ACWS) of the Hawaii Air National Guard, the 193rd Aviation Regiment (Medium Lift) and Detachment 55 Operational Support Airlift (Det 55 OSA) of the Hawaii Army National Guard and the Regular Army's 25th Infantry Division's Combat Aviation Brigade.[6]</ref>[7]
Wish I could be more help. Neat find regardless
