When I was in junior high (which is now called middle school in a lot of places) one of my classmates was sent a Spanish coin off a wreck one of her relatives had found and was in the process of excavating. This would have been a few years before the Atocha was found, which is when the Spanish gubmint started to go after the people who did the work of locating and recovering the cargoes.
Nice pic!
