1918 Gold Sovereign PER

George V was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 until his death in 1936 and was King during World War 1. George was the second son of Albert Edward, Prince of Wales (later King Edward VII), and grandson of Queen Victoria. After his death he was succeeded by his eldest son, Edward VIII.

In 1919-20, the Silver price rose dramatically so .925 silver coins began to made in 0.500 siver. Gold Sovereigns were produced in large quantities early in George's reign - over 30 million in 1911 and again in 1912, although there was no bullion sovereigns issued 1918-1924 (Commonwealth mints did continue mintage).
The 1918 Gold Sovereign Perth 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 (Ottawa) and South Africa (Pretoria) although these regional mints have not made sovereigns since 1932 (although India has produced some recently in a private mint partnership with the Royal Mint). The non-British coins carry a small mintmark ('S','M','P','I','C' or 'SA') just above the date. This 1918 Gold Sovereign Perth was minted at The Perth Mint.

The Obverse is the Monarch's head (George V) 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".

History

Up until 1604 there was a coin called the English gold sovereign and in 1816 when there was the "Great Recoinage" the name was revived. At that time standard gold (22 carat) was valued at £46 14s 6d per troy pound; this meant a £1 coin needed to weigh 123.2744783 grains or 7.988030269 g. The weight is still the same today.

As a historical note: to maintain the Gold Standard, in 1816 the value of silver was set at 66 shillings for one troy pound and silver coins were only legal for denominations up to £2.

The first sovereigns carried the head of King George III and the famous George and the Dragon design by Benedetto Pistrucci (29 May 1783 – 16 September 1855), an Italian engraver who became chief medallist at the Royal Mint.

With high value coins such as the 1918 Gold Sovereign Perth, collectors and bullion investors often worry about forgeries but actually gold coins are very difficult to forge due to gold's unique properties of density and colour. Gold is extremely dense and to use another metal and gold-plate it would result in a coin that is under-weight, over-diameter or half as thick, something that would be spotted very easily. More difficult to spot would be a bullion coin melted down and re-cast as a highly collectable date, but an expert can usually tell these too. You should always use reputable dealers.

The Perth Mint, Western Australia, is Australia's official bullion mint and wholly owned by the Government of Western Australia. The Perth Mint opened in 1899 in response to the discovery of rich gold deposits in Coolgardie and Kalgoorlie.  It was Australia's third branch of Britain's Royal Mint - the others being the Sydney Mint and the Melbourne Mint (both closed).
Australia is a country and continent surrounded by the Indian and Pacific oceans. Australia used pounds, shillings and pence until 1966, when it adopted the decimal system with the Australian dollar divided into 100 cents. The 1oz Silver coins are a particular favourite with collectors around the World and feature the famous Australian animals such as Kookaburra, Kangeroo and Kaola.
