Learn how to recognise and label historical buttons with Deputy Curator Georgina

Postal uniforms have been adorned with buttons since the 1700s, when they were inscribed with the words ‘General Post Office’ for the crew on packet ships. With the introduction of the Penny Black in 1840, the postal service grew, with new jobs requiring unique uniforms. Buttons have come in all different sizes, designs, and materials. So how can you identify them? Read on to learn what questions to ask.

Which crown is it?

The Tudor Crown

The Tudor crown was created for either Henry VII or Henry VIII. It was used by Henry VIII and became part of the coronation for each of his children. The crown was a symbol of power and monarchy. In 1649 Oliver Cromwell ordered it melted down.

The St Edward’s Crown

The St Edward’s crown was made for Charles II in 1661 as a replacement for the destroyed Tudor crown. The crown is made of solid gold, decorated with precious stones and is used in the coronation of modern monarchs.

The best way to tell these crowns apart is to look at the top of the crown. If the top is curved, similar to an upside down ‘U’, this is the Tudor Crown. If however it curves to produce a heart shape, this is the St Edward’s Crown.

Knowing which crown you have will help you to date the button. The St Edward’s Crown was used during the reign of Queen Victoria and later for Queen Elizabeth II from 1954. The current King Charles III and those between Queen Victoria and Queen Elizabeth II used the Tudor Crown, mimicking their cyphers. You can also see slight stylistic differences to the St Edward’s crown of Victoria, with pinched arches, compared to the rounded heart shape used by Elizabeth II.

But what is a cypher?

The Royal Cypher is a way of combining a monarchs’ initials and title, this can either be standalone letters or entwined like a monogram. They often include ‘R’ which stands for either ‘Rex’ or ‘Regina’, which is Latin for King or Queen.

In 1975, uniform buttons were re-designed to include Queen Elizabeth II’s cypher ‘EIIR’ below the St Edward’s crown. This was controversial in Scotland as Queen Elizabeth is considered the first of her name in Scotland, as Queen Elizabeth I of England didn’t rule Scotland. In December 1978 Mr G. Tilling, Chairman of the Scottish Postal Board, wrote a letter to Postal Headquarters in London about the new design explaining that they should have been consulted and “these buttons will not be worn in Scotland.

210,000 buttons had already been distributed and were considered unusable. As an interim measure, the Post Office reverted to the earlier design of block GPO letters below the St Edward’s crown.

This is very similar story to with Scottish pillar box cyphers. To learn more about cyphers and how to spot them on pillar boxes, check out our webpage Royal Cyphers on Letter Boxes – The Postal Museum.

What font is used?

Under the crown design you will find the letters ‘GPO’, this stands for the ‘General Post Office’. The postal service opened to the public in 1635 and became known as the General Post Office from 1660. This name was used up until 1969, when the organisation ceased to be a government department and became a nationalised industry – the ‘Post Office Corporation’.

The font of this text has changed over time. The fancy script came first with the clear block letters appearing later.

What is it made of?

The material of the button is sometimes misleading. Both brass and plastic buttons have been used throughout the 20th and 21st centuries so it’s always best to focus on the crown rather than the material!
