From the pictures it looks nice. The 58/59 fleetside are fairly hard to come by, so they can command a premium compared to the 2 headlight versions.
Any idea if it runs or drives?
At the end of the day, it is "worth" what someone is willing to pay for it. Being an auction, pick your max ahead of time and don't get suckered into a bidding frenzy.
Make sure you check the fees and premiums beforehand and take those into account for your pricing. The local auction house here recently upped the premium from 10% to 15% (plus 3% if not paying cash) plus a $200 flat fee for the honor of getting to buy a vehicle from them.
