Is your £1 coin worth £200?

Finding an error coin is like winning the lottery for collectors. And after reading today’s blog, you’ll be adding another rare error to your Change Checker watch list!

As earlier this month, a pub worker discovered a £1 coin that was minted from just ONE metal – not two – which went on to sell for £205 on the secondary market!

You see, normal £1 coins have a gold coloured Nickel-Brass outer ring and a silver coloured Nickel plated interior, but this rarity was completely gold-coloured. Check it out in the image below…

Understandably this lucky find was immediately added to eBay and the uniqueness of the coin meant there were 24 bids from five interested bidders, before it eventually sold on August 8 for the unbelievable price of £205!

Mad, right?

One explanation for the supposed ‘error’ could be that the coin missed the plating stage during production.

Whilst this is the first time we’ve heard of the ‘error’ being found on a £1 coin, similar stories have been reported on £2 coins before…

The Holy Grail of Bi-metallic Errors

The image above shows what has been described as the Holy Grail of bimetallic ‘errors’ and is the result of the nickel-brass £2 blank not having the inner core section punched out before being struck.

This means that the £2 coin is made from one full piece of nickel-brass, just like the £1 error above – completely contrasting the very idea of a bimetallic coin.

A 2007 monometallic £2 was verified by The Royal Mint and in the email confirming the mis-strike it was mentioned that they had only seen 4-5 similar coins before.

This rare striking error is highly sought after and coins have achieved extraordinary prices in private sales and auctions.

So if you don’t consider yourself a Change Checker, it might be time to rethink as these exceptional error coins could be lying unused at the bottom of your bag.

How much is my coin worth? July 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.

This update sees the Kew Gardens 50p climbing by £9 on the secondary market, taking its median sold price to £156.50!

Kew Gardens
2009 Kew Gardens 50p

Released by The Royal Mint in 2009 to celebrate the 250th anniversary of the Royal Botanic Gardens at Kew, the striking design of this 50p, by Christopher Le Brun RA, features the famous Chinese Pagoda at Kew entwined by a decorative leafy climber.

In 2014, The Royal Mint revealed that only 210,000 Kew Gardens 50p coins had been struck, making it the scarcest UK coin in circulation.

Until this point, the coin had been somewhat overlooked, but once collectors realised just how rare this coin really was, the race was on to find one in their change – a challenge which to this day has coin collectors hunting far and wide for the chance to find one.

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

Football
Olympic Football 50p

There’s also been an increase in the sold prices for the Football 50p, climbing by £7.

Olympic 50ps have long been a favourite amongst collectors, but did you know that only 1,125,500 Football fifty pence pieces entered circulation? It’s definitely the rarest one to look out for and tops our chart as having the smallest mintage figures, which means it is even harder to find than the others.

As we’re now able to get out and spend our cash more, there are bound to be some changes in the coming eBay Tracker updates. We’re certainly excited to see how the sold prices of the top 10 UK coins and banknotes are influenced by this over the coming months!

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.

Since January 2021, there has been a 3.53 point decrease in the overall value of the Top 10 coins and banknotes on the eBay Tracker. After January’s steep increase, it looks as though the Index is levelling out again.

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.

Breakfast (10p) is served! Your Scarcity Index Update…

It’s time for your latest Scarcity Index update, where we reveal the UK’s most sought-after circulation coins of the last three months! As we’ve been able to go out and spend more cash in recent months, how has this impacted our Scarcity Index?

Well there’s been lots of movement across all of our indexes, as new trends have been exposed and one particular coin has moved an impressive 16 spaces!

You can use the updated A-Z 10p, 50p and £2 indexes below to discover how sought-after the coins in your collection really are.

This information has been compiled using data from the Change Checker Swap Centre and presented in the easy to use indexes below, with arrows to signify how many places up or down a coin has moved since the last Scarcity Index.

A-Z 10p Scarcity Index

It’s English Breakfast time this quarter as this 10p has climbed a huge 16 places on our A-Z 10p Index! This is definitely the one to watch

Whilst the top 8 spots have stayed the same, there have been some really big movers towards the middle and lower half of the table. The Ice Cream and X Marks The Spot 10ps have both dropped 10 and 13 places respectfully, with other big movers including the Union Jack 10p (dropping nine places) and the Fish and Chips 10p (climbing eight places).

All of the lower mintage A-Z 10ps have remained strong at the top of the index; the Y, Z, and W 10ps all have a 2019 mintage of JUST 63,000 so it would take some doing to beat them to the top…

Regardless of where they feature in the above index, if you have any of the A-Z 10ps in your collection you should consider yourself very lucky. A maximum of only 304,000 of each design entered circulation!

50p Scarcity Index

We’ve had a shake up at the top of our 50p Index this quarter, with the Judo 50p being bumped down two spaces from second to fourth spot.

Last quarter our top six 50ps hadn’t moved but this quarter we’ve seen Football climb back to second spot for the first time in three quarters!

There’s also been a lot of shuffling in the middle and lower parts of the index, with Roger Bannister climbing an impressive 10 spots and Handball dropping seven.

The ones to watch are definitely Pentathlon (having climbed 10 places last quarter and a further six this quarter) and Shooting, which climbed two places last quarter and a further two places this quarter. We’re excited to see how these coins place in our next update…

£2 Scarcity Index

Whilst the Commonwealth Games £2 coins have remained consistent at the top of our Index, we’ve now got our Olympic trio sitting beneath, with the Olympic Centenary climbing 3 places and the London 2012 Handover and Olympic Handover £2 coins coming in behind.

After climbing 8 places last quarter, the Florence Nightingale has dropped back down again to the bottom of the Index.

The First World War (Kitchener) £2 has climbed up a space after also climbing two spaces last quarter, so this could be one to watch over the coming months…

How your Scarcity Index works

Generally collectors have had to rely upon mintage figures to identify the scarcest coins.  But they only tell part of the story.  Trying to find a good quality coin from 15 – 20 years ago, even for a higher mintage issue, is much more challenging than a more recent issue, as coins become damaged over time and are ultimately removed from circulation.

Additionally, some designs are more hoarded than others by people who might not normally collect coins – the poignant First World War £2 Coin series being an example. Finally, it can be up to a couple of years before the Royal Mint eventually confirms the actual mintage for an issue.

That’s why we have combined the mintage information with two other key pieces of information.

  • How many of each design are listed as “collected” by Change Checkers, indicating the relative ease of finding a particular coin.
  • The number of times a design has been requested as a swap over the previous 3 months, showing the current level of collector demand.

Importantly, as new coins are released and popularity rises and falls across different designs the Scarcity Index will be updated quarterly allowing Change Checkers to track the relative performance of the UK’s circulation coins.

How much are my coins worth?

The Scarcity Index does not necessarily equate to value but it is certainly an effective indicator.  For example, the Kew Gardens 50p coin commands a premium of up to 200 times face value on eBay.

You can use the 6 point guide to help you determine a more realistic value for your coins.

What about £1 Coins?

The £1 Scarcity Index has already been published for the Round £1 coins and, because they are no longer being issued, this is now set in stone.
