The answer to your inquiry does not relate to the mold, but rather to the resulting product. Is the resulting product a utilitarian product? If so, is there a design patent or utility patent covering the product? If not, there may not be any enforcible rights. Is the object decorative, as opposed to functional, e.g., a sculpture? If so, who desighed the object? If you did, the copyright in the object belongs to you, not the person who made the molds. As you can see, there are numerous questions that must be answered before an opinion can be given as to what you can do. However, mere ownership of the molds would not give ownership of the rights in the resulting cast the same way that ownerhip of a blueprint of a building would not give rights in a building constructed using the blueprint.
