Why Is the Undated 20p Coin So Special?
A Historic Minting Error
The undated 20p coin became a sensation because of a rare minting mistake made at the Royal Mint in 2008. That year saw the introduction of a new design for British coinage, featuring the Royal Shield of Arms spread across multiple denominations. During this redesign, some 20p coins were accidentally struck without a date—something that hadn’t occurred in UK currency for over 300 years.
This error happened when the reverse (tails) die, which omitted the date, was paired with an obverse (heads) die that also lacked a date. The result was a batch of coins that broke tradition and gained instant notoriety among collectors.
Why Coin Collectors Prize the Undated 20p
The rarity of the undated 20p coin is a key factor behind its high value. With only a limited number produced before the mistake was discovered, these coins quickly became coveted items.
Additionally, the lack of a date—a fundamental feature of legal tender—adds to its mystique. For collectors, owning a coin with such a unique error represents a piece of history, making it one of the most sought-after modern coins in the UK.
The Story Behind the Minting Mistake
The undated 20p coin error occurred during the production of the 2008 coin series, which introduced a major redesign of British coins. The Royal Shield of Arms design was created to span across multiple coins, with each denomination showing a portion of the shield.
For the 20p coin, the date was traditionally included on the reverse side. However, the Royal Mint opted to move the date to the obverse side as part of the redesign. A mix-up during production paired two dies that lacked the date, resulting in the undated 20p mule coin.
How to Spot the Undated 20p Coin
Finding an undated 20p coin requires attention to detail. Here’s how you can identify one:
- Check for a Date: Examine both sides of the coin carefully. A standard 20p coin will have the date on either the obverse or reverse side. If there’s no date, you may have found the rare undated 20p.
- Inspect Its Condition: Ensure the coin isn’t simply worn or damaged. A missing date due to wear is not the same as the minting error.
- Verify Authenticity: If you think you’ve found an undated 20p, have it appraised by a professional numismatist to confirm its authenticity.
Why You Should Check Your Change
A Treasure Waiting to Be Found
One of the most exciting aspects of the undated 20p coin is that it’s still in circulation. This means anyone could come across it in their change, making the hunt for this coin accessible to everyone—from seasoned collectors to casual enthusiasts.
Valuable Beyond Face Value
At an estimated market value of £50, this small coin is worth 250 times its original denomination. For collectors, this value represents more than just money; it’s a testament to the coin’s rarity and significance in British numismatic history.
The Broader Appeal of Coin Collecting
The undated 20p coin is just one example of how everyday coins can hold extraordinary value. For collectors, these unique finds are not only valuable but also a connection to history and the artistry of coin design.

What to Do If You Find an Undated 20p Coin
If you’re lucky enough to find an undated 20p coin, here’s what you should do next:
- Confirm It’s Genuine: Consult a professional numismatist or a trusted coin dealer to verify the coin’s authenticity.
- Preserve Its Condition: Store the coin in a protective case to prevent scratches or further wear.
- Decide Whether to Sell or Keep: While the coin’s value is around £50 now, its rarity could increase its worth over time. You might choose to keep it as an investment or sell it to a collector.
