Monsters of the Movies Wolf Man kit

[Batty Belfry]

Hello~
I don't post much but am asking for some help if I could.
Does anyone have a good idea what an original unbuilt Monsters of Movies Wolf Man kit could sell for?
Everything is still attached to sprues save for 3 pieces. The box/instructions are beautiful! I saw a price of $140 in an Aurora kit guide published in 1992 but am sure prices have changed since then. I was also told this is the rarest of the 6 monster kits can't prove that. I think a resin kit was done of this monster but this kit is an original.
Could members of the UMA chime in with best guess values, please? I've seen nothing on eBay to help me recently.
Thank you so much for your help, Army~

I've seen them go for up to $250 for a mint still shrink wrapped box. Not really sure what an opened one goes for.
