South African sculptor Coert Steynberg did the bust of L. Ron Hubbard in 1960. It was stated by Coert Steynberg as one of his best work. 10 bronze castings were created. One of the bronze casting is in the possession of the family and they are interested to sell it. I would like to know the market value of the bronze casting that was created in 1960. I am attaching photos of the actual bronze casting.
