"Low mintage – limited edition coins like commemoratives or special releases.

"Minting errors – rotation errors, double strikes, missing details, or misprints.

"Unique designs – special series."

Other coins the collector mentioned in the post were the Kew Gardens 50p, the Wrestling 50p coin from the London 2012 collection and the bronze 20p.

The collector claimed these coins might look ordinary at first glance but could be a "hidden treasure".

He continued: "Always take a moment to check the date, design, and condition – it could pay off!"

The Bank of England launched its £10 note featuring Jane Austen back in 2017.

It's worth remembering banknotes are desirable when you find a specific serial number. For example, the £10 notes with AA serial numbers could earn you the big bucks.

ChangeChecker revealed the serial numbers on a Jane Austen £10 note can be valuable for collectors, particularly if it matches specific dates related to the author.

Key dates include:

• Her birthday - 16/12/1775
• Her death - 18/07/1817
• The publication date of Pride and Prejudice - 28/01/1813

Collectors are also interested in notes with low serial numbers, especially ones which begin with AA01. This serial number is when the first notes were printed, with AA01 000001 being the very first note.

Meanwhile other notable serial numbers include:

• JA01
• JA75
• JA17
• Any "ladder" or recurring number sequences (for example, 001122, 012345) can also be of interest

Think you own one of these in your stash? It's always worth getting advice from a professional who can have it valued for you.
