Q: I have an old Coors Beer sign, 24 by 18 inches, that’s titled “Coors Golden Brewery.” It’s painted on what appears to be the side of an old wooden crate. I searched the price guide on Kovels.com and found one with this description: “Coors Beer, Adolf Coors Golden Brewery, Red-Haired Woman, Colorado.” But that sign was 30 by 38 inches (and worth $2,200). Is what I have of any value?
