I know..I stopped thinking or actually caring about it. I always think "First Strike" in Military terms...So, to me, in my head, in coin universe, the First Strike is the last struck coins from the U.S. Mint for a particular series, that were shipped and stored in the Distribution Facility. The last remaining coins in the Distribution Centers would be First Strikes, hence the Delivery cycle??? this I have heard...Echoing off Planets and Moons from station to station...Even though I'm a CAC Lover, I still always focus on coin first...or in this Rare instance a Medal. I'm not really a Medal Fan but I respect them. This was purchased for a completely different reason....How many FS can be designated...I don't know...how many are there? That can be looked up...
