1824 Half-Sovereign – George IV

George IV was King of the United Kingdom of Great Britain and Ireland and of Hanover following the death of his father, George III, on 29 January 1820, until his own death ten years later. George IV had previously ruled as Prince Regent from 1811-1820 due to his father's mental illness.

George was married to Caroline of Brunswick and they had a daughter, Princess Charlotte, who died following the birth of a stillborn child. As the second son of George III (Prince Frederick) was childless, following the rules of the monarchy on his death George was succeeded by his brother, William IV.

Note that on coin, George IV is often written as Georgivs IIII.
The 1824 Half-Sovereign - George IV is an example of the Gold Half-Sovereign and is a gold coin, being as it's name suggests, half the value and half of the gold weight of a gold sovereign. Today, the half-sovereign is a commemorative coin, not issued every year and often only collected as part of a set.

The Half-Sovereign wa introduced a long time ago, in 1544 during the reign of Henry VII. However it was discontinued in 1604 (along with full sovereigns) and no more were minted until 1817. Production ended again in 1926 (1933 in Australia) and except for a few special issues during the Coronation years, it was 1980 when we saw half-sovereigns again.

As the value is half of one sovereign, that gives the half-sovereign a face value of half a pound or ten shillings - 50p in post-decimal money, although you're going to have to pay somewhat over the gold price if you want to buy one.

The Obverse is the Monarch's head (George IV) and on modern half-sovereigns the Reverse is most often St George and the Dragon (usually the Benedetto Pistrucci version), although other backs have been used.

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 diameter of a half-sovereign is 19.3mm and is only slightly smaller than a full sovereign (22.05mm) so first appearance may confuse inexperienced buyers. You can see in the image on the right, the half-sovereign on the right hand side is quite similar to the full sovereign on the left.

While you can buy half-sovereigns, many collectors only own them as part of a set.

The Royal Mint is the designated place for the UK to mint coins. It dates back well over 1000 years and is a Government-owned company. 

Formed in the reign of Alfred the Great about the year 886, during the period 1279-1812 it was generally referred to as The Tower Mint as it was housed at the Tower of London. The Master of The Royal Mint has included famous figures such as Sir Isaac Newton.

Since 2010 it has operated as Royal Mint Ltd, a company owned by HM Treasury, under an exclusive contract to supply all coinage for the UK although it also produces medals and coins for other countries. It is currently located at Llantrisant, Wales.
The United Kingdom (UK) is the Union of England, Scotland, Wales and Northern Ireland. It is often refered to as Great Britain (GBR). It has a long, rich history.

The orignal coinage was Pounds, Shillings and Pence but since decimalisation on 15 February 1971, it is £1 = 100p, that is One Pound = 100 pence. The coinage of the UK is also a long history, the Royal Mint being established as long ago as 886AD when coins were hammered. Today there is perhaps 30 billion coins in circulation, and many (numismatic) collectors coins and sets are issued frequently in gold, silver and other metals.
