NS Schwesternschaft Pin, Opinions?

[BaselA]

I have no idea on the originality of this, as I have never encountered one. It is unmarked on the reverse, but the material I believe is nickel.

I searched around the web a bit a located some nice, albeit somewhat expensive, marked silver versions. What would the value be for an unmarked non-silver version?
