Those mags are worth about triple because of that Circle 1 marking.

there are 3 major variations which seem to be year specific issued with sp1. circle 1, circle upside down 1 then 3rd is the circle without 1. airforce issued them in wrappers at some point. most common of the types is the one you have the standard circle 1.
