THE SOVEREIGN


Until the 19th century England had struggled to maintain a bimetallic system of currency based on a fixed ratio of value between gold and silver. The problems involved in maintaining this system were complex and resulted at times in revaluations of the gold currency and/or a shortage of silver coinage when the quantity of silver bullion became insufficient to supply the Mint. In 1816 this bimetallism was finally abandoned and England went on the Gold standard. From now on and until the First World War, gold was the single standard of value in the British coinage, and for the first time ever silver coins were minted with an intrinsic value considerably below their face value - the first official token coinage in British history.

THE SOVEREIGN - in 1817 a new gold coin of 20 shillings was introduced which became known as the sovereign. It had a weight of 123¼ grains and was made with Crown gold of the usual 22 carats. Few coin-weights are known for George III. The Royal Mint issued weights dated 1821 and 1823 under George IV, the obverse with ROYAL MINT around a lion passant over crown and the date below. The reverse has CURT (ie 'current') WEIGHT.SOVEREIGN.5D 2½G. The next official issue of weights was under Queen Victoria and these were similar to the previous issue but dated 1842. Similar weights were also made by private individuals with the same obverse but with ONE SOVEREIGN and the maker's name on the reverse. For the next official Mint issue in 1843 a new type is used with the bust of Victoria to left in a dished centre and around the raised edge in incuse letters ROYAL MINT 1843. On the reverse of this issue is 5DW 2½GR in the centre and around the margin CURT WEIGHT SOVEREIGN. There is also a half-sovereign with weight 2DW 131/8GR on the reverse. As with the earlier guineas there are a large number of privately made weights known. Some are similar to the official issues but with a crown, beehive, rose or other design in the centre with the makers name on the reverse. Common words used at this time are:- CURT . CURRENT . CURRENT STANDARD . WARRANTED . WARRANTED CORRECT. One uniface type has a decorative border with a crown over SOVEREIGN and the weight 5D 2½G below. Others are square and have 20S or 1 SOVgn on both sides.

SUMMARY

The weighing of gold coins was at times a complex but necessary part of trade and commerce. Many coin-weights will have been used for a long period and some will possibly have been adjusted illegally or from necessity due to changes from the Mint. Many coins were also current long after they had first been issued indicating that the coin-weights had a long life too. Some coin-weights by the information on them will be fairly easy to identify but for others they will need to be accurately weighed to judge in which period they were used. The following table summarises the information contained in this article. Rare coins for which there are no known coin-weights such as the George-noble are not included. A new category is only used when a type has been re-issued or there has been a change in the weight. The tolerance weight is the lowest at which the coin in theory could still pass as legal tender and should therefore be that for the actual coin-weight.
