Some suggested questions for you to answer for yourself:
The Stingray has how much sentimental value?
If you get a gig which bass would you take - one of the Jazzes?
would you miss having the Precision?
Do you need the money, if so how much? Put the basses in value order.
Dont worry about the kids they probably won’t want anything which old dad had.
Maybe reduce the number 1 at a time and see how much you miss any one of them.
Tough decisions, good luck with making a choice.
