At a wild guess, I would say somewhere between 100-200k. If I were selling it, I'd probably ask 80k. I'm a firm believer in selling low.
As always, a disclaimer: selling jewelery is by no means an exact science. What you have there is nearly perfect for an archer who uses chivalry, but is hurt by the relatively low intensities (everything from 70-80% of max) and the fact that spirit speak isn't normally complementary with archery. But if you found someone with a template which uses all of that and doesn't already have something better, you could get closer to the high end.
