The coinage of Anne's reign remained fairly constant being inaugurated in 1662. Before the Act of Union with Scotland (1706), the arms of England and Scotland remined separate, as shown. After the act the two arms were conjoined on one shield. The word Vigo denotes that 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.
