If he is loose I'd say $50 at most given how rare he is. If you have the packaging and it's still in good condition you could try for $80 to the right buyer.
I've seen more common figures that cost $150 MISB go for $30 loose. There is a ton of value in that packaging on the secondary market. I keep all my Takara packaging plus some Hasbro packaging for rare figures (like SDCC stuff) because if I ever decide to sell them that stupid box makes a big difference.
