Need help to value a couple of LJN figures.

I have the following figures, all 14-Back and in original sealed and mint condition (Not a scratch or bent corner on some of them)

How much would be a fair price?

Panthero x 2
Mongor x 1
Cheetara x 1
Lynx-O x 1

(Bonus: I also have one of those old Wrestling figures, made by LJN. This one is a "Jim Neirdhart" figure, which also is in original/sealed and good condition. I see there's one for 900 bucks on Ebay now. If we have any WWF LJN experts here)

Check the sold completed auctions on eBay if you want to know the current market value. Then you can go from there for base prices.

In regards to Jim Neidhart I think you should be looking for at least $5-600. A single MOC Neidhart sold a while back for just over $500 so I would say asking $66 would be a good amount.

As for the Thundercats I would say you would be looking at the very least $6-700.
