USAF Sheppard AFB 882d Training Group 50th Anniversary Challenge Coin

Got this cool challenge coin from the Health Services Administration School at Sheppard Air Force Base. It's a 50th anniversary piece (1952-2002) for the 882d Training Group. Still in the original plastic sleeve, looks like it was never really handled much. Great little piece of military history if you're into collecting coins or medical admin memorabilia. Blue enamel looks sharp.
