Bass Info Help

[MostlyBass]

I need some guidance on determining the value of some basses. A non-bass playing friend inheriteda number of basses that she wants to sell. We know the value of the double basses (a Nick Lloyd and a Jakstadt!!!!) but I don't know enough about the bass guitars.
Here are three I have taken pictures of so far. Will get more pictures soon.

There's also an Ampeg flip top (new model) with 2nd matching cabinet.

Wishbass
F Bass

- update - got some details on the Wishbass:
Serial #1926
cherry body & neck
Purpleheart fingerboard
J-pickup
oil finish

I only know about the Wishbass. You will probably only get a couple of hundred bucks for that. I would be interested in it at $200.

F Basses are pricey. New, this exact model is worth 4600$ - split this amount in 2 and you have a fair price for used.
