My family has quite a thing for music and some of my uncles have some nice guitars, they wanted to know the value of them, I was also curios.

69 Fender Stratocaster
73 Stratocaster
59 Gibson Acoustic "has no lettering on asde from gibson"
Fender jazzmaster "not sure of year between "65-70"
all my uncles happen to be old men so they have no idea how to find out on their own terms
you could probably get between $10000 and $20000 for the lot seeing as they are from a period where guitar making was quite good
