What Is the Rare 20p Coin and Why Is It Special?
In 2008, the Royal Mint redesigned UK coins, introducing a new shield motif across the lower denominations. During this transition, a “mule error” occurred. A batch of 20p coins was mistakenly struck using the old obverse (Queen Elizabeth II’s portrait without a date) and the new reverse (shield design) that also lacked a date.
This rare combination means these coins have no date at all — a striking mistake in modern minting where accuracy is everything.
It’s estimated that between 50,000 to 250,000 undated 20p coins entered circulation, making them rare but not impossibly scarce. This intriguing backstory significantly boosts their collectibility and value among numismatists (coin collectors).
Quick Fun Fact:
The undated 20p was the first undated British coin to enter circulation in over 300 years!
How Much Could Your Undated 20p Coin Be Worth?
According to reputable sources like The Sun, the market value of an undated 20p depends largely on its condition:
- Circulated (worn): ~£40-£60
- Good Condition: ~£70-£90
- Near Mint/Uncirculated: £150 or more
In some cases, eBay auctions have seen bids nearing £97 for well-kept examples. Truly pristine coins, authenticated by numismatic professionals, could fetch even higher prices at auction houses.
Recent Sales Example:
In March 2024, a certified undated 20p coin sold at a UK auction for £175, reflecting growing demand among serious collectors.
Why Do Errors Like This Matter?
In coin collecting, minting errors can add massive value because they’re anomalies. Most coins are mass-produced to exact specifications, so a mistake like the undated 20p is a “happy accident” that offers:
- Rarity
- Historic curiosity
- Higher collector demand
This principle applies broadly to collectibles: rarity + story = value.
Step-by-Step Guide: How to Spot a Rare 20p Coin
Here’s exactly how you can check if you’ve struck gold with a rare 20p:
Step 1 – Check Both Sides Carefully
Look for a date on both the “heads” (Queen’s portrait) and “tails” (shield design) sides. If there is no visible date, you might have a rare coin!
Step 2 – Confirm the Design
Make sure the reverse (tails side) shows the shield portion introduced in 2008. Compare with a known dated version if unsure.
Step 3 – Examine the Condition
The better the condition, the higher the value. Use gloves when handling the coin to prevent oil damage.
Step 4 – Authenticate if Necessary
For maximum sale price, professional authentication can add credibility. Reputable dealers like the British Numismatic Trade Association can assist.
Step 5 – Get Multiple Opinions
Before selling, get valuations from two or three independent sources to ensure you’re setting the right price.
Selling a Rare 20p Coin: Best Practices
Selling a valuable coin can feel overwhelming, but following these tips will help you get top value:
- Do Not Clean the Coin: Cleaning can severely reduce the value.
- List Accurately: Include clear, high-resolution images and a full description.
- Use Trusted Platforms: Sites like eBay, Spink, and coin-specific auction houses are recommended.
- Consider a Valuation: A valuation from a professional can set a realistic price expectation.
- Keep Records: Document the coin’s discovery, condition reports, and appraisals for transparency with buyers.
How to Protect and Store Your Rare Coins
Once you find a rare coin, protecting its value is crucial:
- Use Acid-Free Holders: Purchase coin holders made from non-PVC, acid-free materials.
- Store in a Cool, Dry Place: Avoid moisture and heat, which can damage coins.
- Insurance: Consider insuring rare coins, especially if their value exceeds £100.
