General Description: Sovereigns

The 2018 Gold Sovereign Proof is an example of the Gold Sovereign and is one of the most ubiquitous of all coins and much sought after by both coin collectors and bullion investors. Sovereigns have been minted since 1817 (in Britain 1817-1917, 1925 and 1957 on). At coins fairs you often hear the dealers refer to these coins as Sovs.

Besides being minted in Britain, Sovereigns have been made in Australia (Melbourne, Sydney, Perth), India (then Bombay, now Mumbai), Canada (Ottowa) and South Africa (Pretoria) although these regional mints have not made sovereigns since 1932. The non-British coins carry a small mintmark (‘S’,’M’,’P’,’I’,’C’ or ‘SA’) just above the date. This 2018 Gold Sovereign Proof was minted at The Royal Mint.

The Obverse is the Monarch’s head (Elizabeth II) and the Reverse is most often St George and the Dragon, although other backs have been used and are of interest to collectors. The Reverse often gives the Sovs a new term, like “ShieldBacks”.
