Elizabeth II
- Queen of the United Kingdom and the Commonwealth realms: 1952–2022
- Dynasty: House of Windsor
- Predecessor: George VI
- Successor : Charles III
- Regime: Parliamentary constitutional monarchy
Elizabeth Alexandra Mary was born in London in April 1926. She married Philip Mountbatten in 1947 and acceded to the throne in 1952 upon the death of George VI. She was 25 years old when she became queen and reigned over the 15 Commonwealth realms. Among others, these include the United Kingdom (of course), Canada, New Zealand, the Bahamas, and Jamaica.
Her coronation at Westminster in 1953 was the first ever to be broadcast on television. She celebrated her Diamond Jubilee (60 years on the throne) in 2012. In 2015, she broke the record for longevity of reign previously held by her great-great-grandmother, Queen Victoria. A great many coins and a great many banknotes featuring the effigy of the Queen were issued by the United Kingdom and the Commonwealth realms during her reign.
She passed away in September 2022, having celebrated her Platinum Jubilee (70 years on the throne) just a few months earlier. Her eldest son then acceded to the throne as Charles III.

Bronze
Bronze (not to be confused with brass, although usage of the two terms varied in times of yore) is an extremely ancient alloy with origins going back to the period around 2,000 BC. Also known...wait for it...as the Bronze Age (who would have guessed?). Back in ancient times, a proportion of 10% tin was added to copper. It was used in particular for luxurious objects such as swords, helmets, hairpins, and even chariot ornaments.
That is by no means insignificant though, as when putting on a bronze helmet you would already find yourself with an extra 3 kilos or so on your head. Add to that your sword and armor…let’s see you advance quickly now!
The heavyweight of alloys one might say*.
The first Western bronze coins probably date back to the end of the 4th century BC and Greece.
Although the coins may be ancient, it is more difficult to date the appearance of a specific word for this alloy. The earliest record is a Venetian manuscript in Greek dating from the 11th century, but it is not impossible that it was in use earlier.
Nowadays, the bronze used in coinage is an alloy of copper (majority) and tin (minority) along with other metals such as zinc, for example, which improves the castability, or nickel, which produces a harder alloy. Its main qualities are undeniably its great resistance to corrosion and mechanical wear as well as...its aesthetic aspect.
The patina of bronze can vary, ranging from verdigris to brown through to black.
*Actually, puns aside, copper and cupronickel have a greater density, for example.
An “AU(50-53)” quality
As in numismatics, it is important that the state of conservation of an item be carefully evaluated before it is offered to a discerning collector with a keen eye.
This initially obscure acronym comprising two words describing the state of conservation is explained clearly here:
About Uncirculated(50-53)
This means – more prosaically – that the coin has circulated well from hand to hand and pocket to pocket but the impact on its wear remains limited: the coins displays sharp detailing and little sign of being circulated. The number (50-53) indicates that at least half of the original luster remains. Closer examination with the naked eye reveals minor scratches or nicks.
You might be wondering why there are different ranges of numbers behind the same abbreviation. Well, we’ll explain:
The numbers are subdivisions within a category, showing that the state of conversation is the same but coins may be at the higher or lower end of the scale. In the case of AU, the range (55-58) indicates that the luster is better preserved in than a similar coin described as (50-53).
