Copper mist isn't exceptionally rare but the price depending on what year/style and condition. We also tend to stay away from pricing kettles here flat out but I will say that prices may start at $50-75 for one in normal user condition and upwards for those really old ones and/or in exceptional shape. If you are looking for maximum $ then eBay is the only way to go. You are welcome to list your grill in the member sales and trades section but please don't use the site for auctions.
