[QUOTE="GDJMSP, post: 3663397, member: 112"]While I readily agree that the OP's coin is a modern reproduction often sold in gift shops and the like, when it come to this - - actually it does. But only under certain circumstances, and it only occurs in salt water. On shipwrecks, when silver coins become exposed to the salt water and encrustation takes place, in other words coral grows on the coin, or silver artifact, that coral takes on a black color. When the same thing happens to gold coins, or gold artifacts, the coral takes on a green color. So when a diver is working a wreck and finds blackish colored coral, he gets a bit excited because there just might be silver inside that coral. And if he finds greenish colored coral he gets even more excited because there just might be gold inside it ! I said might above because sometimes other metals, but not precious metals, can cause coral to take on the same colors of green or black. So ya never know for sure what ya got until ya clean it up. But yeah, gold and green do go together under the right circumstances.[/QUOTE]
