A Gold Sovereign is a gold coin first issued in 1489 for Henry VII of England and still in production as of 2009. While the coin typically had a nominal value of one pound sterling or 20 shillings, the sovereign was primarily an official piece of bullion with no mark of value anywhere on the coin itself.
The name "sovereign" comes from the majestic and impressive size and portraiture of the coin, the earliest of which showed the king facing, seated on a throne, while the reverse shows the Royal coat of arms on a shield surrounded by a Tudor double rose.
