Yes, you read that correctly, that tiny little coin in your pocket could actually be worth some serious bread. But before you start frantically digging through your change jar, let’s take a closer look at why this specific type of 20p is so valuable.

You see, back in 2008, the Royal Mint accidentally produced a batch of 20p coins without a date. While this may not seem like a big deal, it actually caused quite a stir among collectors. The undated 20p became an instant rarity and quickly gained popularity among coin enthusiasts all over the UK. But how much is an undated 20p piece worth, exactly? Well, the value can vary depending on a few different factors, such as the condition of the coin and the current market demand. But, at the height of its popularity, these little gems were being sold for over £50!

Now, before you start thinking about how much you can make off your old loose change, keep in mind that finding one of these coins is no easy feat. While it’s definitely possible to come across one in your everyday transactions, the chances are quite slim. But the hunt is what makes collecting so enjoyable, isn’t it? Who knows, maybe you’ll be lucky enough to find an undated 20p hiding in the depths of your pocket change.

What is an undated 20p coin?

An undated 20p coin is a rare type of 20 pence coin that lacks a year stamp indicating the year it was minted. These coins were produced due to an error during the minting process that caused the year stamp to be omitted. Only a limited number of these coins were released into circulation, making them a valuable find for coin collectors.

History of the Undated 20p Piece

The 20p coin has been in circulation in the UK since 1982, but it wasn’t until 2008 that an error resulted in the production of undated 20p coins. The Royal Mint, the United Kingdom’s official mint, produces all the country’s coins. The undated 20p coins were produced between 2008 and 2009.

  • The undated 20p coin originates from a die error at the Royal Mint. The die is a metal stamp used to produce coins, and a missing date on one of the dies used to produce the 20p pieces resulted in the undated coins making their way into circulation.
  • The undated 20p coin is the first coin in British history to have no date printed on it since Charles II began dating coins in 1670.
  • More than 200,000 undated 20p coins have entered circulation, but it is unclear how many were minted in total. This is because the Royal Mint doesn’t disclose this information.

Despite their origins as an error, undated 20p coins are now considered collectibles. Some people have even made a profit selling the coins online or to collectors. The Royal Mint itself acknowledges their uniqueness, stating on their website that the undated 20p coins “remain legal tender and can be used as normal, but as collectors’ items their value will probably exceed their face value over time.”

If you’re curious about the value of an undated 20p coin you may need to enlist the help of an expert coin valuer. The coins’ value is dependent on factors such as their condition and rarity. In general, the value of undated 20p coins has increased since their release, with some selling for as much as £100 (almost $140 USD) online.

Year Produced Rarity Average Value
2008 Rare £50-£100
2009 Common Face value

If you happen to come across an undated 20p coin, it’s worth consulting an expert valuer. Not only could you find out it’s worth considerably more than its face value, but you’d also be learning a little piece of British coin history.

How to identify an undated 20p coin?

Undated 20p coins are rare and can be worth a significant amount of money to collectors. Here are some ways to identify if you have an undated 20p coin:

  • Size: The undated 20p coin is the same size as the regular 20p coin at 21.4mm in diameter and 1.7mm in thickness. However, the weight of the two coins is different – the undated 20p coin is slightly lighter at 5g compared to the regular 20p coin at 5.0g.
  • Edge lettering: The edge lettering of the undated 20p coin is different from the regular 20p coin. The edge lettering on the undated 20p coin reads “TWENTY PENCE” six times, with each word being rotated by 180 degrees, while the edge lettering on the regular 20p coin reads “TWENTY PENCE” once and is not rotated.
  • Design elements: The design elements on the undated 20p coin are also slightly different from the regular 20p coin. The undated 20p coin does not have a date on the obverse side and depicts the portrait of Queen Elizabeth II facing right. The reverse side shows a segment of the Royal Shield with the Lion Rampant of Scotland, with the denomination shown as “20 PENCE.”

If you suspect that you have an undated 20p coin, it is important to take it to a coin expert or dealer who can authenticate the coin and determine its worth. Some undated 20p coins are worth only a few pounds, while others can fetch thousands of pounds at auction.

If you are interested in collecting undated 20p coins, it is important to do your research and learn as much as possible about the history and rarity of these coins. A good place to start is with a trusted coin dealer or numismatic society.


Identifying an undated 20p coin is not difficult if you know what to look for. Look for the differences in size, edge lettering, and design elements. If you suspect you have an undated 20p coin, it is important to get it authenticated and appraised by a trusted coin expert. Happy collecting!

Factors that affect the value of an undated 20p coin

Undated 20p coins are rare and highly sought after amongst coin collectors. The value of these coins can vary depending on several factors which include:

  • Rarity – The rarity of an undated 20p coin can significantly affect its value. The scarcer it is, the more valuable it becomes. For example, if a minting error led to a small number of these coins being produced, their value would be higher than if it was produced in large quantities.
  • Condition – Similar to other collectibles, the condition of an undated 20p coin is an important factor that determines its value. If the coin is in excellent condition, then it is worth more than a coin with scratches, dents, and other imperfections.
  • Demand – The law of supply and demand comes into play in the world of coin collecting as well. If there is a high demand for a certain undated 20p coin, its price will rise accordingly.

In addition to the above factors, other elements that can affect the value of an undated 20p coin include the method of production, the history behind the coin, and the reputation of the issuing mint.

Interestingly, the undated 20p coin was not a mistake but rather a test run by the Royal Mint to check their equipment’s accuracy. A small batch of these coins were subsequently released into circulation, making them a scarce and desirable item amongst collectors.

To give you an idea of the value of these coins, below is a table indicating their estimated worth based on the condition:

Condition of the coin Estimated value
Uncirculated £100 – £200+
Lightly circulated £10 – £50
Heavily circulated £1 – £5

In conclusion, the value of an undated 20p coin is determined by several factors, including rarity, condition, and demand. It is important to keep in mind that the value of these coins can fluctuate based on various factors, so it’s best to consult with a reputable coin dealer before undertaking any transactions.

Rarity of undated 20p coins

Undated 20p coins are one of the rarest coins in circulation in the UK. These coins were mistakenly printed without a date in 2008, and it is believed that only around 200,000 of these coins were released into circulation. The Royal Mint quickly corrected the issue, making the undated 20p coin one of the most sought-after coins for collectors.

  • Undated 20p coins are so rare that they can sell for up to £1000 – or even more – in online auctions.
  • Many coin collectors have been searching for this coin for years, but it remains elusive due to its rarity.
  • One of the reasons for its rarity is that the Royal Mint only released a limited number of these coins into circulation, making them difficult to find today.

On top of that, collectors and enthusiasts have been keeping these coins in their personal collections, making it even rarer to come across an undated 20p coin today.

One of the reasons why these coins are so popular among collectors is that they represent a historic moment in the Royal Mint’s history. While the error was corrected shortly after it was discovered, the undated 20p coin has become a much-coveted collector’s item.

Denomination Number Produced
Undated 20p Coin 200,000
