Model collectors. Need help!!

I know its not mopar related but i need to see if i could get help with pricing. My great uncle just passed and his daughter is selling stuff to fund his funeral. Some guy came in and offered her $5 for this model. She called me and i told her hell no. I just need some help and maybe an offer if someone wants is. It seems to be all there and the box is in decent condition.Thanks all.
