Are you ready to discover the mighty beasts of the sea and sky?

The Royal Mint have revealed a brand new 50p series celebrating Mary Anning and her fossil discoveries on the Jurassic coast.

Plesiosaurus 50p

The second coin in the series has JUST been released and it celebrates one of the Jurassic Coast’s greatest marine reptiles, the Plesiosaurus.

The Plesiosaurus was about 4.5 metres in length and is estimated to have weighed about 45 tonnes (that’s about 7 elephants!)

But what makes this Jurassic Giant so unique, is the power of its bite! It’s estimated that the Plesiosaurus had the largest bite force of any known animal and with teeth as sharp as needles, there’s no doubt this reptile dominated the oceans!

If you look closely, you can even see this Jurassic Giant’s teeth in the design of this BRAND NEW coin!

This series is already proving incredibly popular with collectors but today you can secure the brand new 2021 UK Plesiosaurus 50p for your collection in Brilliant Uncirculated quality for JUST £4.50 (+p&p). To secure yours in official Change Checker packaging, simply click here >>

The ‘cutting tooth lizard’ (as it’s otherwise known) is one of the largest ichthyosaurs to have been discovered by Mary Anning in Lyme Regis, Dorset.

This apex marine predator hunted in the deep ocean millions of years ago, but now this prehistoric beast has been brought to life once more – its likeness captured in exquisite detail on this brand new 50p.

This was first coin in the series to have been issued and you can secure one for your collection in Brilliant Uncirculated quality for JUST £4.50 (+p&p). To secure yours in official Change Checker packaging, simply click here >>

The Unsung Hero of Fossil Discovery

Mary Anning is remembered as being one of the greatest fossil hunters and paleontologists to have ever lived.

At the start of her career, she claimed her excavations were merely to explore her ‘curiosities’. Later, she was to discover remains of some of the greatest creatures to have ever swam in our shores and soared in our skies.

Famous in her home town of Lyme Regis, Dorset, Anning’s work left a legacy of fossil hunting, paleontology and science

Dinosaur fans and historians alike, still flock to the seaside town in their thousands every year to learn more about her discoveries and to try and unearth their very own creatures in the sand and rocks!

Sought-after Series

This collection follows in the gigantic footsteps of the 2020 Dinosauria 50p series, which brought us the Megalosaurus, Iguanodon, and Hylaeosaurus 50p coins.

These coins were a definite numismatic highlight of 2020, with collectors quickly snapping up these dino-mite coins for their own collections. This was the FIRST-TIME ever that Dinosaurs featured on a UK coin and this year the theme continues with three prehistoric creatures being celebrated on coins.

In 2021, we get up close and personal with the Jurassic giants of the sea and air, with the Mary Anning 50p Collection.

Each coin in the collection has been designed by renowned British palaeo-artist Robert Nicholls with the expert guidance of Sandra Chapman of the Earth Sciences Department of the Natural History Museum.

It’s fair to say that the influence of the designs from the Natural History Museum will certainly make these coins popular with dinosaur fans and collectors alike!

If you’ve been keeping up with Change Checker, then you’ll have seen we’ve been counting down to the 50th anniversary of Decimal Day, but if you’re new here and aren’t too sure what Decimal Day was all about, we’ve got you covered with our Top 10 Facts that you should know about Decimalisation!

  1. For centuries before Decimalisation, Britain’s coinage consisted of pounds, shillings, pence, farthings, crowns, half pennies… the list goes on.
  2. The decimal debate was first raised in 1847 by Sir John Bowring, who proposed a call for the UK’s currency to be changed to a currency based on units of ten.
  3. The first decimal coin, the florin, was issued before 1971 but it wasn’t until 1st March 1966 that the Chancellor of the Exchequer, James Callaghan, announced that pounds, shillings and pence would be replaced by a decimal currency, with a hundred units in a pound.
  4. The changeover was a huge task. Businesses and the general public needed all the necessary information prior to the change, in order to make the transition as smooth as possible. There were nationwide public information campaigns in place, from posters to television broadcasts.
  5. The changeover was so big, that The Royal Mint’s production capabilities at Tower Hill were not up to the sheer volume of coins required to be produced. So, decimalisation literally drove The Royal Mint to South Wales, where it’s been ever since!
  6. During the preparations for the changeover, almost six billion coins were struck at The Royal Mint’s site in Wales!
  7. The new 5p and 10p coins were introduced in 1968 and were the same size and value as the existing one and two shilling coins, to make the transition easier for the British public.
  8. It was in 1969 that the first seven sided coin – the 50p – was introduced to replace the 10-shilling note as a more economical alternative!
  9. On Monday 15th February, 1971, the transition was complete and the, 1p and 2p coins were also introduced. The Decimal Halfpenny was also introduced in 1971, but it was eventually demonetised in 1984.
  10. Since Decimalisation, we’ve seen over 75 50p designs, over 60 different £2 coin designs, and a complete re-design of our £1 coins specification, and of course not forgetting the very first commemorative 10p coins!

So, there you have it! Our top 10 facts about Decimalisation! Have you got any memories of D-Day? Let us know in the comments below!

2021 marks 50 years since our UK coins turned decimal, in the biggest numismatic change seen in centuries.

In celebration of this significant anniversary, The Royal Mint issued not one, but TWO Decimal Day 50ps in 2021. The reverse designs are the same, but that certainly can’t be said for their obverses…

The first version of the Decimal Day 50p, available exclusively in the 2021 Annual Coin Set, features the original Arnold Machin portrait of Her Majesty The Queen on the obverse – the same obverse used for the UK’s very first decimal coins.

However, the individual coin which was released later in January, featured Jody Clark’s fifth portrait of The Queen instead.

So why did The Royal Mint revert back to the Queen’s first decimal effigy for this new issue? Join Change Checker as we take a closer look…

Spot the Difference

The 50p available in the Annual Set which features the original Machin portrait on the obverse, quickly caught the eyes of collectors as this was the first time we have seen The Royal Mint revert a previous portrait of HM Queen Elizabeth II on a base metal UK coin.

Marking 50 years since our UK coins went decimal, it seemed only fitting that this coin should include Machin’s obverse design.

But, when the Decimal Day 50p was individually released later in January, collectors had the opportunity to get their hands on a second version of this coin, as Jody Clark’s portrait of The Queen featured on the obverse.

So with two versions of the 2021 UK Decimal Day 50p out there, this coin is set to become a real talking point among collectors!

Arnold Machin Portrait

The significance of this anniversary and the fact that the Machin portrait of HM QEII was the first to be used on the UK’s 50p, makes for the perfect excuse to revert back to this previous effigy on the exclusive Decimal Day 50p within the Annual Set.

The UK’s very first decimal coins (5p, 10p, followed by 50p) actually entered circulation before 1971 and as they were circulating together with pre-decimal currency, a new portrait of The Queen was commissioned to help the new coins stand out.

Arnold Machin’s new portrait showed The Queen wearing a tiara given to The Queen by her grandmother, Queen Mary.

We love the fact that collectors have the chance to see this previous portrait reused on this brand new 50p and it certainly makes for interesting collecting!

But that’s not all, as this is not the first time we’ve seen different obverses used on the same coin…

2015 Battle of Britain 50p

In 2015, The Battle of Britain 50p shot to fame as collectors were quick to spot that there were THREE different versions of the coin, with different obverses on each of them.

The Brilliant Uncirculated 50p was issued early in 2015 and was quickly dubbed an ‘error’ coin. The coins, which were sold in presentation packs, had been struck without the denomination in either numbers or writing anywhere on the coin. Chancers were quick to play to this, with some managing to sell on the coins for near to £100 each on the secondary market.

After the controversy surrounding the coin erupted, the Royal Mint confirmed that the 50p intended for circulation later on in the year would have the ’50 PENCE’ denomination. But was this after they had realised their mistake?

So how did this coin end up with three different obverses?

Each version of this coin has caused a stir in the collecting world. Not only does this Battle of Britain 50p fail to feature a denomination on the Brilliant Uncirculated version, but the obverse is different for each finish used for the coin – a first for a UK commemorative coin.

In 2019, a brand new re-issued Brilliant Uncirculated version of the Battle of Britain 50p (from the 2019 50th Anniversary of the 50p Military Set) saw Jody Clark’s portrait and the 50 PENCE denomination – making this the FOURTH version of this 50p!
