Could someone help me determine the value of a Night Force scope?

I have a 2.5-10x50mm scope with the illuminated NP1-PT (Police ranging reticle) in excellent condition with ARMS #22 throw lever rings.

What's this baby worth?

The scope has seen limited use on an Armalite AR-10T.

Thanks

This is the NP1-RR reticle, which varies slightly from the PT (Police version) as far as how the ranging works.
