A RARE 1p coin could be worth up to £500 on eBay if it features a specific marking, an expert has said.

The ancient coin is from 1902 and features King Edward VII on the front. The reverse features a design of a seated Britannia, a female figure which appeared on British coins for centuries.

An expert has revealed that a rare 1p coin could sell for up to £500 on eBay if it features a specific marking.

The ancient coin is from 1902 and features King Edward VII on the front.

The reverse features a design of a seated Britannia, a female figure which appeared on British coins for centuries.

She is seated on rocks or a wall, with one foot on a pile of stones and holding a scepter in her hand.

There is an image of the sea in the background, and the tide is either high or low in the coin.

A social media post from a user called the Coin Collecting Wizard on TikTok said coins with a marking showing the tide as being low are more valuable.

The user said: "The low tide penny is a certain variety of the 1902 where the sea line is lower than the usual penny.

"Low tide coins are worth considerably more than their high tide counterparts, and if you're lucky enough to find a 1902 low tide Penny, then you're looking at around £500 in uncirculated condition."

Uncirculated coins refer to money that hasn't been in circulation for public use and has retained its original condition.

So for example you would not get the coin as change if you paid for something in a shop.

It is also important to remember that a regular 1902 coin which shows the ocean tide as high is not worth as much money.

The Sun found one which sold for just £3 on eBay earlier this month.

It is worth keeping an eye on your spare change as it could be worth a lot more than you think.

Other rare coins which could be worth more include the One Penny which dates back to 1893, but it's the production error which makes it a valuable find. 

The ancient coin features Britannia on the back and the reverse of the coin is the usual Queen Victoria bun head, which is a feature on many coins from this era. 

What makes the coin valuable is an error with the number three in the date at the bottom of the coin. 

Under the number three of the error coin it looks like there is the start of a number two.

If the coin features this it could be worth up to £600.
