This is interesting, some of Anthony Bourdain's possessions were auctioned off by an online auction house, including this: https://bid.igavelauctions.com/Bidding.taf?_function=detail&auction_uid1=5555151 I wonder if he had other kaiju items in his collection.
Some of those X-Plus pieces weren't made in large numbers. I have no idea whether this one is actually worth $800 though.
I think it sold for that much mainly because it was from his collection. If you look at the other stuff that went up for sale, a lot of that stuff went for crazy prices. So I think the price tag was more so due to the name associated with the toy as oppossed to the toy itself. https://bid.igavelauctions.com/AuctionHelp.taf?page=4&s=N&sort=4&st=2&days=3650&bo=1&keyword=AB1A https://bid.igavelauctions.com/AuctionHelp.taf?page=1&s=N&sort=4&st=2&days=3650&bo=1&keyword=AB1A
