Got this of eBay the other day. I won't admit to how much I had to pay to get it, but it was worth it. I worked on the DCM staff at Bentwaters from 82-84, and recently got back in touch with my old roommate and coworker from not only my days there, but Chanute (tech school) previous to it.
I have been trying to keep off eBay as it is somewhat costly, and I dropped a small fortune on a couple of Springfield M1911A1s a week prior; but I couldn't resist this one...

I have never seen a 81 TFW DCM coin previously, and I sure hope they don't start showing up on eBay for $5 each!
Cheers! M2
