How much are these mags worth? (Swiss Arms)

[Styrak]

I have a bunch of mags for my Black Special, including 2x factory shorty 5 round Swiss mags. I don't really like them or want the shorty mags, and already have enough so I'm wondering about how much they're worth?

Someone told me I could get $50 each. What's your take?

I've seen the shorty's for 50 retail lately.

I think ~ $50 is what people are paying ... I don't like the short mags myself, so they aren't worth much to much!
