Because the founding fathers (along with the founders of almost every other country) wanted their coinage to be as close to the intrinsic values of the metals as possible. Making a 1 cent piece out of silver would be far too hard because it would be easily lost and would be too small to really use, making it out of gold would be even harder, so the only solution would be to make it out of copper (actually, there were proposals and trial coins minted with a small amount of copper with a hole and then a silver "plug" would be inserted to equal one cent, this design was scrapped when it became evident that it would cost more to make than it was worth with the added labour costs) in fact, the older pennies were much larger than the small coins we have now, they were more similar to a half-dollar in size than a penny we use today, this was because of how large they needed to be to equal approximately a cent of copper (keep in mind that during this time we had a gold standard and a dollar was equal to 1.604 grams of gold). Today however, rampant inflation and the demise of the gold standard means that pennies used today are actually zinc with a small layer of copper on the top of them. Pre-1982 pennies are actually worth almost 3 cents a piece in copper content, however, because they are illegal to melt down or export, there are few people who will buy them at their true value.
For hundreds of years, British low denomination coins were made from copper as a relatively cheap means of manufacture.
Copper was a little too soft to make a hard wearing coin, so from 1860 they were made from bronze (which consisted of about 95% copper) which made the coins a lot more hard wearing and durable.
Eventually copper became too expensive to be making low denomination coins and from 1992, all British Pennies and 2 Pence coins were made from copper plated steel, a much cheaper and durable alternative.
Since 1992, British Penny and 2 Pence coins have been made from copper plated steel.
The change to steel coins was an economic decision, steel being much cheaper than the 95% copper the Penny and 2 Pence coins were made from.
The new steel coins are copper plated to protect the coin from rusting and to also give the coins a visual distinction from other coins.
British 1 and 2 Pence coins have been made from copper plated steel since 1992.
Prior to 1992, bronze (97% copper alloyed with a very small quantity of zinc and tin) was chosen as a relatively cheap and durable metal to make low denomination coins from.
Towards the end of the 20th century, copper became too expensive to be making even low denomination coins.
There were no copper 50 Pence coins minted, they are all made from a copper/nickel alloy giving them a silvery appearance. If your coin is copper coloured, it is either very seriously tarnished or somebody has plated it. Modified coins have no collector value.
The two coins are a ten-pence coin and a one pence-coin. The one-pence coin is the one that is not a ten-pence coin.
One fifty pence and one five pence, one of them is not a five pence.
This is a common riddle and misconception. 1 of the 2 coins isn't a 20 pence, but the other one will be, thus, a 20 pence and 10 pence add up to 30 pence.
Copper has not been removed from British coins, but the Royal Mint has not produced pure copper coins since 1860. The current British 1 Penny and 2 Pence coins are made from copper plated* steel since 1992. Previously they were made from bronze which contained 95% copper. (Some bronze 2 pencecoins were issued in 1998 within the circulating coinage). The 5, 10 and 50 Pence coins are made from a cupronickel alloy containing 75% copper and 25% nickel. In 2011, the copper content of the 5 and 10 pence was dropped and subsequent mintage uses nickel plated* steel. The older cupronickel issues will be withdrawn gradually in a longer-term changeover plan. The 20 Pence coins are made from cupronickel containing 84% copper and 16% nickel. The One Pound coins are made from a nickel-brass alloy containing 70% copper, 24.5% zinc and 5.5% nickel. The bimetallic Two Pound coins are made from an outer ring (annulus) of nickel-brass (76% copper, 20% zinc and 4% nickel) and a core of cupronickel (75% copper and 25% nickel). *Full plate cf. cladded coins.
A Two Pence coin weighs 7.12 grams. There are 50 Two Pence coins in a Pound. One Pound worth of Two Pence coins weighs 356 grams.
Neither. Since 1992, all British 1 Penny and 2 Pence coins have been made from steel with copper plating. This is an international trend to reduce the cost of manufacturing low denomination coins.
A 20 pence and a 5 pence. One of them is not a 5 pence.
The other one is !
It is not illegal, but the bus driver has no obligation to accept large quantities of small coins when fewer larger denomination coins would suffice. It would be an act of goodwill on the bus drivers part when he has to count the coins and keep the bus on schedule. One Penny and Two Pence coins are only considered Legal Tender up to a combined total of 20 Pence.
British decimal 1 and 2 Pence coins have never contained nickel. From their introduction in 1971, the 1 and 2 Pence coins were made from bronze, consisting of 97% copper, 2.5% zinc and 0.5% tin. From 1992 onwards, they have been made from copper plated steel. A 25% nickel content is used in the British 5, 10, 20 and 50 Pence coins and gives the coins their silvery appearance. The Five Pound coin and the centre of the Two Pound coin also contains 25% nickel. The One Pound coin has a 5.5% nickel content.
The 'copper' coins are in fact copper-clad steel nowadays, although older ones are bronze. From 2011 5p and 10p coins are in nickel-clad steel, although earlier ones are cupronickel. 20p and 50p coins are minted in two slightly different copper-nickel alloys. Pound coins are in nickel-brass, while two pound coins are in nickel-brass with a cupronickel centre. See the link below for more information
