A coin collector would pay more than £5 for the coin, if it was uncirculated and in Mint condition, or a Proof coin. However if you were to go into a bank and exchange the coin for other currency, they would only give you the face value of £5's worth.
It's worth exactly 5 pence.
£5
Face value.
Five pounds
Such a coin does not exist. The English have never produced a 4 Pound coin.
A 1889 gold 5 pound coin is worth 5 pounds of gold, while a 1889 2 pound gold coin is only worth 2 pounds of gold.
As I type this the value of 1 pound of gold is $18,040.00
The Royal Mint produced no British Five Pound coins from 1938 to 1979 inclusive.
It is a common coin, worth a pound or two if in perfect condition.
The British Five Pound coin is Legal Tender in Britain and can be accepted as payment for goods and services anywhere in Britain. However, the Five Pound coin was minted for collectors as a souvenir or investment and were not intended as circulating currency. The Royal Mint advises that "most retailers will refuse to accept them". If your Five Pound coin is in mint condition, it is probably worth more than Five Pounds.
These coins are still in circulation. Unless they are in mint condition, they are worth One Pound.
If it is a proper one and not a mule it is worth £614
