My uncle had 4 guitars and my cousin inherited them when he died and my cousin wants to know how much their worth.

1. the first one is a gibson les paul custom (serial #290000).

2. the second is a rickenbacker semi hollow (cant find serial)

3. a rickenbacker solid body (surprising small)

4. a fender telecaster MIM in a color thats discontinued (i think)

If any one can tell me an estimate of how much any of them are worth that'd be great.
My Gear:

Epi Les Paul Standard
Fender 48th Street Strat
Vox Valvetronix AD50VT
Martin Koa Acoustic
Some crappy unnamed bass

email the companies with the serial and they should be able to date them and give an estemate
