Where should I post a "how much is it worth" question

[67Mach1]

Not sure where to post this, but i have a how much is it worth question.

Ive got a 71 longbed bed that had a wood floor in it at one time. Sides are solid with some surface rust.

I dont plan on using it myself but do not know what it might be worth or even if this might be a desireable option.

Any one got an idea. Or is it a waste of time and should I just try to sell the bed sides alone.

Thanks,

thomas
