not an authentic fender, old and used... maybe 200 dollars to someone who wants it. You can buy authentic made in America and new for 500 dollars. I have no idea if it is collectable or not. If it is then obviously the price may go up.
Somewhere between $500-$1000 depending on who wants it.
If it's a nice bass and still in good condition it could be about 500 to 1000$.
