It's hard to put values on the Big Bolts, but i've seen them in comparable shape to yours bring as high as $4500-$7500, & you may not belive this, but I've seen nice 'ol Big Bolts sell as low as $750-$1500. I purchased a very nice, running, low milage (13000mi.) '49 4400, back in the early '90's for $350. I felt guilty, leaving the old guys house, for it that cheap. It had been originally owned by a local Golf course,since new, for maintenance, & was too old to be useful to them, so it was just an old unusable truck to them. When it comes to big trucks, it all depends on who's looking for what, at that particular time, & who owns it. Exposure plays a big part also, when selling.
