According to Provident Metals, the half sovereign is a gold British coin that was first minted in 1544 under Henry VIII. The coin features the face of the English ruler in power during the time it was minted. Gold half sovereigns were last minted in 1926.
Half sovereigns are roughly the same size as a nickel and contain .1177 Troy ounces of .913 gold. The reverse side of the coin features St. George slaying a dragon. This design was created by Benedetto Pistrucci, whose initials are inscribed below the dragon. Special editions of the half sovereign were minted until 1980. Commemorative editions, bullions and proofs of the coin were printed after 1980. Production of the half sovereign stopped in 1604 until the coin was reintroduced in 1816.
