Which Mel Fisher Coin do I have?

Hi, I saw on here that someone had written something about an old Spanish coin from a ship wreck? I have one that my Grandfather gave to me. And Its got a Kings head on the front and on the back like a person with their arms like an Egyptian with a bird on one arm. Can you tell me where it could be from?. I know it was gotten from Mel Fisher store in Florida.

From your description it’s not likely Spanish.

Can you post a picture?

Added–What do you mean when you say “arms like an Egyptian?”
