The coinage of Anne's reign remained fairly constant after the inaugural design in 1662. Before the Act of Union with Scotland (1706), the arms of England and Scotland remained separate, as shown. After the act the two arms were conjoined on one shield. The word Vigo indicates the coins were struck from gold captured from the Spanish at the Battle of Vigo Bay (1702). Although silver coins bearing the Vigo inscription are less rare, the three gold denominations bearing the symbol are all extremely rare.
