Need help determining price of double V eyepiece

[theritz]

I have one of these ones gathering dust and am willing to sell it. But... at what price? I can't really estimate since I don't see them going around much.
Does anyone of you knowledgable folk know? Tia!

Not sure of the price but its an early Vixen.

It's a Vixen orthoscopic from around the 1980's as Charic says. They were supplied with Vixen scopes back then. I've seen them for sale for £20-£25 in good condition (which yours appears to be in). 

They are good quality eyepieces but the trouble is that very few people are looking for the .965" format eyepieces these days.
