Coca-Cola Cast Iron Hand

I bought this on ebay. I am new to the whole collection business, but I found this on ebay and the story behind it is that the person I bought it from, bought it at an auction. I have no idea what it is or if it is actual Coke memorabilia or not, but the Coke emblem on the bottom of the hand is applied to the hand itself and was not added later. However, it looks as if the person who owned it prior to me shined up the Coke emblem well. Does anyone know what this is?
