The remarkable story of when a British 2 pence weighed the same as a Mars Bar…

Today I’d like to tell you the story behind my all-time favourite British coins – the Cartwheel Pennies. Not only are they the heaviest and largest coins ever issued for circulation, they were also issued for ONE-YEAR-ONLY. Here’s the story…

Throughout the 18th century silver prices increased, which resulted in a substantial decrease in the amount of silver pennies that were being minted. This led to a lack of small change and businesses were finding it difficult to pay their employees with the current coinage.

Two of the largest coins ever issued in British history

Subsequently, a trend began where independent Mints started striking copper half penny and penny tokens. Most of these tokens were being minted at the ‘Soho Mint’ in Birmingham, which was actually the very first Mint to be powered by Steam.

Whilst this was not legitimate money it solved the issue and it took off – companies all over Britain were ordering personalised tokens.

However, the ‘solution’ meant there was a problem…

The British Government had lost control of the coinage. In an attempt to regain control, they instructed Soho Mint to strike 480 tonnes of copper pennies and 20 tonnes of copper twopences. These were to be the first regal British coins of the denominations to be made of copper, and the very first official British coins to be struck using steam power. 

8 times heavier than today’s 1p and 2p coins

The coins were large! In fact, the 1 pence weighed an incredible 1oz and the 2 pence weighed 2oz – that’s the same weight as a Mars Bar and almost 8 times heavier than the current 1p and 2p coins. At that size, it’s hard to believe these ever jangled in the pocket of our ancestors! 

The coins weighed so much becauses they  were struck in pure copper and their intrinsic value corresponded to their actual face value. Their design was simple – a  portrait of the monarch at the time, King George III on the obverse and Britannia on the reverse.

The dramatic size of these coins and their unusually wide raised rim is why they became known as ‘Cartwheel’ pennies.

Issued for one-year-only

The modern 1p coin compared to the 2oz 2p coin

The ‘Cartwheel’ pennies were designed this way to prevent counterfeiting, but their size and weight made them cumbersome and unwieldy. They were immediately unpopular with the public as people didn’t like carrying them around – the two-pence was an INCH and three-quarters in diameter and a quarter inch thick. There were soon calls for them to be discontinued and shortly after, the coins were redesigned.

Due to the rise in the price of copper, the intrinsic value of the coins soon exceeded their face value and subsequently the majority of these coins were melted down.

This meant, the coins were issued for one-year-only, which automatically makes them two of the must-have modern coins and key coins in any British collection.
