What will the King Charles III 50p be worth?

Any avid collectors knows the worth of a scarce coin.

A look at the Change Checker Scarcity Index will show you just how sought-after UK coins can be.

The coin at the top of the 50p Scarcity Index is the Kew Gardens 50p – just 210,000 entered circulation in 2009 and they still (over 13 years later) fetch around £100 on secondary market sites.

But, you can be sure that if you find one in your change, you’ll own a small piece of history – the very first coin of King Charles III’s reign. And remember, it’ll never be worth less than its face value of 50p.

When will there be more coins?

The Pioneer of Computing

Boasting an impressive career in calculus, astronomy, and arithmetics , Charles Babbage held the title of Lucasian Professor of Mathematics at Cambridge University.

The 1820s saw Babbage’s development of his ‘Difference Engine’, which was a machine that could perform mathematical calculations. Initially constructed as a six-wheeled model, it was later developed into a bigger, better, and more complex machine – Difference Engine 2.

However, his fame as a computer pioneer largely came from his invention, the Analytical Engine. It could perform any arithmetical calculation using punched cards, as well as a memory unit to store numbers – the fundamental components of today’s computers.

Babbage’s ideas were well ahead of their time, making him a perfect addition to The Royal Mint’s Innovation in Science series.
