Have you tried asking on non ladder? Or doing a quick search if anyone is ISO this? That'll pretty much tell you what it's "worth" to someone.
That's honestly the best chance you have of finding a price.

Cuz last wish is shit, perfect or not. You'd have to find someone making a kicker or prey on someone making a smiter in stupid fashion.
It's rarely even worth the hrs needed to make it.

Good luck with sale
