How are coins made? The 5 stages of coin production

Have you ever wondered how the coins in your change are made?

From the drawing board to your pocket, there’s a lot that goes into the production of UK coins, and so we’ve put together a 5 stage infographic to break it down for you…

How are coins made? The 5 stages of coin production

1) Designing

First, The Royal Mint’s marketing team look at possible themes and develop a brief for the designer. They work with internal artists, graphic designers and external artists such as competition winners.

The designer sketches a concept either by hand or on a computer and this is sent to The Royal Mint Advisory Committee for feedback and approval.

The final stage in design is to send the coin to the Queen for final sign off of the design.

It was actually revealed recently that the Queen took a particular liking to the 2019 Stephen Hawking 50p, which has proven to be a big success and a hugely popular design this year.

2) Moulding and Engraving the Master Die

Designs are transferred and sculpted onto a plaster mould 5 times the size of the coin.

This model will be scanned and stored as a digital image to be used by an engraving machine.

The transfer-engraver reproduces the design onto a master die the same diameter as the coin to be struck.

This will be used to make the dies that will actually strike the coins.

3) Blanking

Sheets of metal are pressed into the exact thickness of the coin required and then rolled into coils.

These huge coiled strips of metal are then cut into the correct shapes by blanking presses.

The presses punch out blank discs with a pressure of around 60 tonnes, creating coins at a speed of 850 strikes per minute!

The blanks are checked before being annealed and blanched to create a lustre suitable for coining.

4) Striking

To transfer the design onto the blanks to be struck, the coin blank is pressed between two dies using a hydraulic press.

The variable pressure of the press is up to hundreds of pounds per square inch.

This forms the shape and design of the finished coin, striking up to 25,000 coins every hour!

5) Inspecting, Sorting and Bagging

The final stage involves checking the coins for imperfections and sorting them into the correct denominations or designs.

They are wrapped and stacked in bags to be stored in ‘the long room’, ready for despatch.

The Royal Mint and cash distribution services regularly review the amount of coins in circulation and it’s only when they are short of a particular denomination that stocks will be called from The Royal Mint, and these coins will be issued into circulation, ready and waiting to be found in your change!

I don’t know about you, but the next time I check my change I’ll certainly be considering the journey the coins have been through to end up in my purse and the incredible production process that goes into creating UK coins.
