Do Roca Rey sculptures have any value?

I am looking for information on a bronze sculpture (head) labeled "Roca Rey 48"|||They are not the most valuable things in the world, but if you are able to find a serious art enthusiast, you could make a bit of money. Depending on if it is an original piece and not a mass modeled copy(there are many) you could be in luck. My best suggestion is to put it on ebay if you are looking to sell it, otherwise treasure it in you home for years to come.
