BB King autographed guitar value

Anyone know what the value of an Gibson Lucille guitar autographed by BB himself would be worth? I have a chance to get one, but have no idea of its value.

I don't really know, but from what I've heard is that typically signed guitar is worth the fair market value for that used guitar, plus $100.00-300.00, depending on who signed it.

he signed a LOT of guitars

To me, the value is sentimental. He signed one for me a years ago ('92 gibson Lucille). It will be a family heirloom for future generations, but for me it is not just a "collectable." I've played mine in the best and worst of places (though my primary electrics have been and will always be Teles). There's no shortage of BB signed guitars out there, they may appreciate in value many years after he's gone. But the reason to have one should be: to have one. A connection to a the man.

I wouldn't count on any added value from the sig. Rarity usually drives value on stuff like that, but you never know what the right fan might pay.
