vintage conch sea shell & corals, large branch corals,& natural history specimens

Estate collection of vintage coral and a conch shell... we have no idea where these were collected, I'm sorry! The corals are 9" and 9 1/2" long, and the conch is about 8 1/2" long. They're all about 30 to 40 years old at our best guess from the other items in this estate.
