They were made from 63 to 71-72. They seem to bring 150 to 300 most times, depending on condition. I used to see them at yard sales for like 25 bucks, and I passed on them. I guess the value depends on if it is a good player. These "b" brand guitars can be great, and they can be real dogs, so the value is mostly in how it plays. I wouldn't expect a significant collector market interest. These were the guitars kids who wanted to play guitar got for Christmas, not the guitars they WANTED to get, so the value is always going to be pretty low compared to the higher end stuff from the same vintage. 60's and 70's big store catalog fodder, really, but if they play well, they often have a unique sound, and can be pretty cool. The models with the gold foil pickups are the 'best' to get, as the pickups seem to be popular for a loFi kind of sound. I think Ry Cooder had a guitar with these pickups, so they are often worth more than the price of the whole guitar.
