I'm not even sure if I will sell these, but I have the following sets that my parents picked up at a flea market 30 years ago. Who knew they invested in Lego long before me.  Anyway these are new in box still, of course there is some shelf wear but curious what some of you would price these at.

Set 948 - Go-kart
Set 955 - Mobile Crane

Thanks for your suggestions

948 200-300 (used goes $50ish)

955 300-400 (used goes $80ish)

There is a new 955 on ebay for $1000. Unlikely to sell at that price but you could keep an eye on it. 

Thank you for the response. I have searched Ebay here and there but usually didn't find anything "new".  

Crazy that sets 40 years old carry about the similar value as sets of modern day.
