Valuation: Pathfinder Kingmaker Adventure Path 2nd edition limited hardcover

I have one of these: https://paizo.com/products/btq02du7?Pathfinder-Kingmaker-Adventure-Path-Special-Edition Which I believe was exclusive to a crowdfunding campaign, or perhaps a limited stock thereafter.

It's not in shrink wrap but it has barely even been opened or touched, so like New condition.

I can't find any online discourse about its value, now that it is out of print. Any insight would be appreciated, thanks.
