£1 Coin Printing Error: A Rare Find Worth Up to £500

Experts claim to have spotted a rare £1 coin printing error that could be worth up to £500.

The error is a micro-engraving around the rim of the coin that indicates it was printed in 2016 instead of 2017.

To spot the error, use a microscope or a phone camera with a zoom feature.

Checking the mintage number can also help determine the coin's value.

The £1 coin lost its legal tender status in 2017, but can still be deposited in some banks.

Some high street banks in the UK accept the round £1 coin.

The £1 coin has been in circulation since 1983 and was replaced by a 12-sided coin in 2017.

The 12-sided coin, or "round pound," is a more secure alternative to the traditional round £1 coin.

The value of a pound coin is exactly one pound, but rare versions can be worth more.

Experts advise checking the coin's serial number and condition to determine its worth.
