I have seen some interest in Fire King but it is local. As a matter of fact the market seems healthy in Southern Deleware but weak in PA. These pieces are not of course setting records at auctions, but the items are seperated in lots in one area and not done so in another. I'm not sure if these pieces will sustain\increase value over time or if the accumulation is pure collecting? Ebay is full of pieces for a price analysis but with shipping I don't think in strong demand. If the piece was double stamped on the bottom would it be worth more like a coin?? For this piece I would not really think so..
