Ferrari 250 SWB Berlinetta and Daytona Racer

Hello all!
I'm trying to help a friend sell some car kits. Her Father passed away a few years back and he left a huge collection.

I can not find a price for the two kits. Does anyone have a guess as to how much I can sell these for? :confused:

Italeri Ferrari 250 SWB Berlinetta 1:24 (No 674)

Italeri Ferrari Daytona Racing 1:24 (No 669)

Both kits are open

Thanks much!
Mary
