To calculate the number of ten pence coins in three pounds, we first convert three pounds to pence. Since there are 100 pence in one pound, three pounds is equal to 300 pence. Next, we divide 300 pence by 10 pence (the value of each coin) to find that there are 30 ten pence coins in three pounds.

Silver and copper alloy. A sixpence was a silver coin equal in value to six pennies, or pence. Under the British pre-decimal pound/shilling/pence (£sd) system, a pound was valued at 240 pence. One pound was equal to 20 shillings and a shilling was equal to 12 pence. Up to the reign of George V, all silver coins had a silver content of 92.5% silver and 7.5% copper, called sterling silver, which was the standard set by Henry II. In 1920, during the reign of George V, the silver content of all British silver coins was reduced to 50%.
The current pound coins are: The penny, the two pence coin, the five pence coin, the ten pence coin, the twenty pence coin, the fifty pence coin, the pound coin, and the two pound coin. There are also crown sized (American silver dollar sized) commemorative coins, early decimal crowns were valued at 25 pence, later ones are valued at five pounds at face value, though often the collector value exceeds the face value, and many shops do not take them. There are also many obsolete British coins, including all the pre-decimal coins, and the decimal half-penny, along with various bullion coins which are legal tender but have metallic values that far exceed the legal tender value.
26.5 pence This is not accurate. It depends on the year of the money. If the money was from the time when coins were .925 silver, then 12 shillings and sixpence would be worth 20 pounds, 62 pence in today's money (as of 1/18/2016) assuming you don't add any numismatic value on top of that. .500 silver coins would be worth 11 pounds, 15 pence. Even base metal coins would have to be put through an inflation calculator to arrive at an accurate amount in today's money.
12 pence
A five pence coin is worth 5 pence, and 7 pennies are worth 7 pence, making the total value 5 + 7 = 12 pence. Since each 2p coin is worth 2 pence, you can determine how many 2p coins equal 12 pence by dividing 12 by 2. Thus, 12 pence divided by 2 pence per coin equals 6. Therefore, 6 two-pence coins have the same value as 1 five pence coin and 7 pennies.
