The 50 Pence coin is still in use. It is equal to half a pound (GBP).
No. The "New Pence" coins are British, Canada has their own currency. The British 5, 10 and 50 "New Pence" coins are no longer legal tender in Britain.
If you refer to the British decimal Five Pound (Crown) coin, they have been legal tender since 1990 when they were first introduced. The Five Pound coin assumed the mantle of "Crown" from the discontinued 25 Pence coin. The Five Pound coin, the 25 Pence coin and the predecimal Crown (Five Shillings) all have the same dimensions. Although the Five Pound coin is legal tender, there is a reluctance by some businesses to accept them due to their unfamiliarity. Any bank will accept them and the Post Office has a stated policy of accepting them for any Post Office related goods and services.
The Royal Mint advises that all general circulation British coins have a purpose. Coins cost too much to produce to have useless coins in the currency, which is one reason why the Half Penny coin is no longer in use. Each higher denomination coin reduces the need to carry larger quantities of smaller denomination coins. Without the 10 Pence coin, you might need to carry 10 Pennies, 5 x 2 Pence coins or 2 x 5 Pence coins, or a combination of any and all. The stated reason for the introduction of the 20 Pence coin was to close the gap between the 10 Pence and 50 Pence coins.
No. The One Shilling coin was to be replaced by the 5 New Pence coin after 1968. The One Shilling coins circulated for quite a while after decimalisation and were finally withdrawn and demonetised in 1990 on the introduction of the new, smaller 5 Pence coin.
There is no British 2 cent coin. The Brits have a 2 Pence coin, which is currently the second lowest denomination British coin in circulation. Up to 1992 they were made from bronze, from 1992 onwards, they are made from copper plated steel and are 25.91 mm in diameter.
From the introduction of decimal currency in Britain until 1981, all decimal coins, except the 25 Pence coin, had the words "NEW PENCE", "NEW PENNY" or "NEW HALF PENNY" inscribed across the top of the reverse, with a numeric value at the bottom. The use of the word "NEW" was intended to assist with the distinction between old and new currency. From 1982 onwards, the "NEW" was dropped. There was a little minting accident in 1983 on the 2 Pence coin and a number of coins were struck with the word "NEW" on them.
It depends on what question you are asking: When was a coin with the denomination of Two Pence first used in Britain? -- The silver Two Pence (or Half Groat) coin was used in Britain as far back as 1351 as a circulating coin, and continues to this day as a part of the four-coin Maundy Money set. When was the large copper Two Pence coin minted? -- The "Cartwheel" Two Pence (so called because at about two inches in diameter, close to a quarter inch thick, and weighing the better part of two ounces, it was almost as big as a cart's wheel) was produced only for a single year in 1797. It was found to be too large and heavy for daily use and was quickly eliminated. When was the currently circulating decimal Two Pence coin first issued? -- The first of the decimal coinage in Britain (100 pence to the Pound, as compared to the old Lsd [Pounds-Shillings-Pence] system) were produced in 1968 - they were 5 and 10 Pence coins. The first Two Pence coin was not produced until 1971 - it was called Two New Pence from 1971 through 1981, and Two Pence from 1982 onward.
The answer depends on the country whose currency you are interested in. Different countries use different currencies with different coinage. For example: the US has a 25 cent coin but not 20 cents. The UK has a 20 pence coin but not 25 pence.
Rhodesia did not use decimal currency until 1974. The coin would have to be Rhodesian 2 shillings and 6 pence.
You would have a small dilemma. Comment: You might have a "sixpence" in "old money" and a decimal 5p coin. (How do we know when we've got the right answer to riddles?) Another idea: Perhaps the wording should have been "one of the coins isn't a 10 pence coin". In which case it's that answer that says: You have 10p and 1p, because one coin isn't a 10p, but the other one is.
the first coin in circulation in medieval England was the penny. it was made of silver. 12 "pence" equaled a shilling and 20 shilling's equaled a pound (240 "pence"). although the term shilling was probably in use by the 1200's, only the "pence" was produced until many years later.
