What denomination is the coin? "New Pence" were introduced in 1968 when Britain eliminated its old coinage system and adopted a 100-based system like most other countries. New Pence (since 1982, called just "pence") are issued in denominations of 1p, 2p, 5p, 10p, 20p, 50p, £1 (100p) and £2. The pound is currently worth about $2 U.S. so you can effectively figure your coin's value by taking its denomination in pence and multiplying by 2 to get cents.
Decimal currency was introduced in Great Britain on the 15th of February, 1971. From then, there were 100 (New) Pence to the Pound (Sterling). The 5 New Pence coin which replaced the Shilling was introduced in 1968 along with the 10 New Pence coin which replaced the Florin. The Shilling coins still circulated along with the 5 New Pence coins until 1990, when the 5 Pence coin was reduced in size and was subsequently no longer visually identifiable as the equivalent of the Shilling coin.
The coin is still worth face value in Britain, and it converts to 71 cents US as of 14 June 2016.
A Bailiwick of Jersey two pence coin is worth its face value of two pence in Jersey currency. However, its actual market value can vary based on factors like condition, rarity, and demand among collectors. Generally, it may be worth slightly more than face value to collectors, especially if it is in uncirculated condition. For precise valuation, it's best to consult a numismatic expert or reference current market prices.

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.
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.
The current British 5 Pence coin is 18 mm in diameter. The 25 Pence coin is 38.5 mm in diameter, more than twice the diameter.
Assuming it's a current British 2p coin dated 1968 or later, in average condition it's only worth face value - roughly US 3¢
In order to make 50p using only 2p coins, you would need 25 of them. This is because each 2p coin is worth 2 pence, so 25 coins would equal 50 pence. This calculation is based on the fact that 100 pence make up £1, so half of that amount would be 50 pence.
