Assuming it's a current British 2p coin dated 1968 or later, in average condition it's only worth face value - roughly US 3¢
A 20 Pence coin is a British coin worth one fifth of a British Pound (GBP). A "nickel" is a US 5 cent coin. At current exchange rates (Jan 2011), the British 20 Pence coin is worth about 32 cents USD.
The 5 pence coin is worth only around 8 cents in US currency, or 5 pence in the UK.

Ten British Pence = Sixteen US Cents £0.10 = $0.16
A two cent US coin is larger in size than a ten cent US coin.
The US has never denominated coins in pence, only cents. And in any case "pence" is plural so no coin would show the denomination "one pence". If by any chance you have a large copper coin about the size of a half dollar with the words ONE CENT on the back, you have what's called a Large Cent.

Not much I'm afraid. The set, which comes in a blue wallet and contains Five and Ten Pence coins dated 1968 and Half, One, and Two Pence coins dated 1971, is valued at about US$2.00 according to the Standard Catalog of World Coins.
The answer will depend on the currency being used. For example, the US does not have a 20 pence coin which the UK does, conversely, the UK does not have a 25 pence coin.
A fifty pence and a ten pence. the one that is not a fifty pence is the ten.
It is in common circulation and worth 2 British Pence, or about 3 cents US/Canadian. It is a common coin and worth no more than face value.
