has anyone made a replica of this?
Welcome, @aquaman. That's a cool one. There aren't many JJ Trek experts here, but perhaps @NickyTea will know something about this prop. Chances are very good the original was made by Maggie Schpak of Metal Arts Studio in Glendale. I know she did some work on the new films.
Call me crazy, but the stretched metal star that makes up the bottom half of the medal looks an awful lot like the Red Squad cadet pin seen in the DS9 season six episode "Valiant". Hmm...
I thought the same thing!
absolutely. But then again, Abrams always uses touches like that to reflect of the history.
