The British Pound coin, along with other British coins, is made from a nickel brass alloy which is a relatively cheap and durable alloy.
With the exception of the 20 and 50 Pence coins all British coins are presently round. The 20 and 50 Pence coins are heptagonal or seven sided.
I have no idea and, it will probably never be known, however, the Royal Mint produced more than 614,881,000 general circulation coins during the reign of Edward VII for use within Britain and the colonies and countries of the British Empire who used the British currency at the time. This figure does not include British coins minted at Mints other than the Royal Mint, non-general circulation coins such as gold Five Pound, Two Pound, Sovereign and Half-Sovereign coins, Proof or especially struck coins, and it does not include coins minted at other mints for the use of other British Empire countries.
British coins are different from all other coins because they are British coins. The coins of all countries need to be different so that we can tell them apart. What is legal tender in one country, is not legal tender in another country.
In 2010, the Royal Mint produced the following British general circulation coins - Two Pound coins - 2,015,000 One Pound coins - 38,505,000 50 Pence coins - 510,090 20 Pence coins - 91,700,500 10 Pence coins - 25,320,500 5 Pence coins - 180,250,500 2 Pence coins - 38,000,000 1 Penny coins - 421,002,000 A total of 797,303,590 British coins. These figures do not include any of the Proof or bullion coins or the 2012 Olympic commemorative coins. Neither does it include the coins made for the 16 other countries the Royal Mint is contracted to produce coins for.
The first British Five Pound note was issued in 1793. It was white and printed only on one side, with no pictures. The first British Five Pound note with a picture on it was issued in 1957 and featured a helmeted Britannia on the front. All subsequent issues of the British Five Pound note have featured Queen Elizabeth II.
There were no British Ten Pound gold coins minted in 1902, or any other year prior to decimal currency.
The British One Pound coin is made from a nickel-brass alloy. No country could afford to make One Pound coins from gold. In most years, the Royal Mint, as do other Mints around the world, produces a range of collector coins. Some of these coins are made from precious metals including gold and silver, amongst others. These coins are not intended for general circulation and they are priced accordingly to reflect the values of the metals they are made from.
Because the Pound is stronger than most other currencies. There are less British Pounds in circulation than, say, American dollars or Euros. Because of this, it takes more Dollars or Euros to equal the equivalent amount of British Pounds.
