I'd offer $25, because the grates look like they need to be replaced. As far as it having a collector value, that's hard to say. It has the sweeps (one touch) so it's not older than 40 years. Looks like it's been drilled into, that'll hurt resale value. But hey, it's a Chocolate, and that's never a bad thingIts about an hour away from me 1 way. I honestly wasn't even wanting to buy another. How much are they worth?
