Did You Know This About Decimalisation? Top 10 Facts!

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!

How much is my coin worth? January 2021 eBay Tracker Update!

Good news Change Checkers – your latest eBay Tracker and Valuation Index is here!

Whilst the secondary market can be a bit of a minefield, we’ve put together an easy way for you to see how much the Top 10 UK coins and banknotes are selling for right now.

eBay Tracker

Find out which coins and notes have been the key movers and shakers in the updated eBay Tracker below.

We’ve seen a huge jump in price for the Undated 20p, increasing by a huge £9! This coin dropped in value in the last eBay Tracker so it’s interesting to see it climb to £50 this month.

This coin is regarded by many as the Holy Grail of change collecting, and back in 2008, the undated 20p saga encouraged an entire country to start carefully checking their coins.

Undated 20p

This mule coin came about when the new Royal Shield 20p coins were struck for circulation, with no date on the reverse. The old die was accidentally used, meaning a batch was issued with no date on either side of the coin.

The undated 20p became the first coin in over 300 years to enter circulation without a date and it’s estimated by The Royal Mint that no more than 250,000 coins made it into circulation.

So, there’s no surprises people are prepared to pay a pretty penny on the secondary market to secure one for their collection!

2018 Sir Isaac Newton 50p

There’s also been an increase in the sold prices of the 2018 Sir Isaac Newton 50p, jumping up by £6.00.

As the 2018 Sir Isaac Newton 50p is a strike your own version, this indicates that collectors are likely heading to secondary markets to get hold of these types of coins, as The Royal Mint Experience remains closed.

With less cash also being used in the past few months because of the current climate, it’s clear this has influenced collector behaviour on the secondary markets too, as people are unable to exchange coins in the same ways they were previously. This therefore drives the price up, as demand for the coin increases.

Additionally, with more time being spent at home and people seeking new hobbies to keep themselves entertained, new collectors are perhaps becoming more aware of rare and collectable coins that might be worth owning and as a result, are heading to the secondary market to get hold of one.

But will we continue to see the price of this coin rise on the secondary market as we head back to a new kind of ‘normal’? Only time will tell and we’ll have to wait for the next eBay Tracker update to find out!

As collectors are unable to source coins in the usual ways due to the current climate, it’s interesting that we’ve seen some big changes this month, as people head to secondary markets to secure coins for their collection.

Valuation Index

Overall, there’s been a 1.3 point increase value for the Top 10 UK coins and banknotes since June’s update and this is no doubt due to the increase in price for 7 of the coins in the tracker.

After an impressive spike in our last update, we’ve seen another increase in January – taking it to the highest we’ve seen since the Tracker started!

My coin isn’t on the eBay Tracker

The eBay Tracker follows the movements of the Top 10 UK coins and banknotes, however if your coin doesn’t appear on the tracker you can use our 6 point guide to help determine realistic a value for your coin.

So now that you’re up to date with our latest eBay Tracker, will you be selling any of the coins in your collection or will you continue to save them? Let us know in the comments below.

How does the eBay Tracker work?

The Change Checker eBay Tracker takes the last 9 sold prices achieved on eBay and gives the median price achieved (rounded to the nearest 50p). By taking the median, rather than an average, we avoid skewing created by one or two excessive prices achieved.

Please note that the Change Checker eBay Tracker is only ever designed to be a guide as to prices achieved on eBay. Prices may vary depending on collector demand and the quality of the coin being sold. It does not provide any guarantee as to future values of coins.


If you’re interested in coin collecting, our Change Checker web app is completely free to use and allows users to:

– Find and identify the coins in their pocket
– Collect and track the coins they have
– Swap their spare coins with other Change Checkers
