$150 each is definitely on the higher side at first glance, but for original pre-ban Colt mags with steel followers and correct markings, that’s kind of where the market has gone. A lot of the newer production Colt-pattern 32-round mags run closer to the $20–30 range , but they’re not in the same collectible category. If those are clean and truly pre-94, collectors will pay a premium—it really comes down to whether you’re buying for use or for originality.
