This interesting charm is in the shape of a sailing ship (maybe the Mayflower) that opens to reveal a figure that resembles a Pilgrim inside. There is a hinge mechanism that allows the top to lift open.
This charm is 7/8 of an inch wide and in very good condition with a slight amount of wear. It is not marked, but I guarantee it to be sterling silver. It originated in Great Britain and not all English silver is marked.
