Welcome to our comprehensive FAQ about the 10p coin, covering its size, weight, validity, and practical uses. Whether you're a collector, a curious citizen, or someone who found an old 10p in your pocket, this article answers the most common questions with clear, factual information.

What is the 10p coin?

The 10p coin is a decimal subdivision of the British pound sterling, worth one-tenth of a pound.

Introduced in 1968, it was originally known as the ten new pence coin and was equivalent in value to the old two shilling coin. The coin is legal tender throughout the United Kingdom and is commonly used in everyday transactions. It features the portrait of the reigning monarch on the obverse and various reverse designs, including the Royal Arms and, since 2008, a segment of the Royal Shield. The current 10p coin is made of nickel-plated steel, having changed from cupro-nickel in 2012 to reduce costs.

How big is a 10p coin?

The 10p coin has a diameter of 24.5 millimeters and a thickness of 1.85 millimeters.

It weighs 6.5 grams. These specifications have remained consistent since the coin's introduction in 1968, except for a slight weight reduction in 1992 when the coin was made thinner. The size is similar to that of a US quarter, but the 10p is slightly larger in diameter. Collectors and vending machines rely on these precise measurements for identification and acceptance.

When did the 10p coin change size?

The 10p coin was reduced in size in September 1992.

The original 10p coin, introduced in 1968, had a diameter of 28.5 millimeters and weighed 11.31 grams. The smaller version, with a diameter of 24.5 millimeters and weight of 6.5 grams, was introduced to align with other European coins and reduce production costs. The old larger 10p coins were demonetized and ceased to be legal tender in 1993, though they can still be exchanged at the Bank of England.

Is a 10p coin worth more than 10p?

Most 10p coins are worth their face value of 10 pence, but certain rare or collectible versions can be worth significantly more.

For example, the 2018 'A to Z' series of 26 different 10p designs has some rare letters that sell for up to £10 or more. Additionally, coins with minting errors or those in uncirculated condition from certain years can fetch higher prices among collectors. However, the vast majority of 10p coins in circulation are worth exactly 10 pence. If you have a 10p coin with an unusual design or date, it's worth checking its potential value online or with a coin dealer.

How much does a 10p coin weigh?

A current 10p coin weighs exactly 6.5 grams.

This weight has been standard since the 1992 resizing. Before that, the larger 10p coin weighed 11.31 grams. The weight is crucial for vending machines and coin counting devices. For reference, the 10p coin is heavier than the 5p coin (3.25 grams) but lighter than the 20p coin (5 grams). The weight is also used by collectors to authenticate coins, as counterfeit coins often have slight weight deviations.

Can I use a 10p coin in vending machines?

Yes, 10p coins are widely accepted in vending machines, parking meters, and other coin-operated devices across the UK.

These machines are calibrated to recognize the 10p coin's specific diameter, thickness, and weight. However, older machines may not accept the newer nickel-plated steel versions introduced in 2012, which are slightly magnetic. If a machine rejects a 10p coin, it might be due to wear or a machine calibration issue. Always check that the coin is not bent or excessively worn, as this can also cause rejection.

What is the rarest 10p coin?

The rarest 10p coin is the 'K' for Kew Gardens from the 2018 A to Z series, with a mintage of only 210,000.

This coin is highly sought after by collectors and can sell for up to £100 or more in uncirculated condition. Other rare letters in the series include 'A' (Aardvark), 'E' (Elderflower), 'L' (Loch Ness), 'M' (Marathon), 'P' (Post Box), 'R' (Robin), 'V' (Village), 'Y' (Yorkshire Pudding), and 'Z' (Zebra). The rarity is due to the low mintage numbers for certain designs, making them valuable finds in pocket change.

How to clean a 10p coin?

It is generally not recommended to clean a 10p coin, as cleaning can damage its surface and reduce its collector value.

If you must clean a coin, use lukewarm water and a mild soap, gently rubbing with your fingers or a soft cloth. Avoid abrasive materials, chemicals, or ultrasonic cleaners, as these can scratch or discolor the coin. For valuable coins, it's best to leave them as-is or consult a professional. Proper storage in a coin holder or album can prevent tarnishing without the need for cleaning.

Final Thoughts

The 10p coin is a staple of British currency, with a rich history and a surprising variety of designs. Understanding its specifications, value, and rarity can enhance your appreciation of this everyday coin.
