A miniature masterpiece: the UK’s smallest coin

At first glance this may appear to be an artist putting the finishing touches to a painting – but these tiny figures stand at little over 20mm! Created by Roy’s People, they depict in miniature Antony Dufort creating his 2015 Britannia design – which features on the United Kingdom’s smallest coin.


Weighing one fortieth-ounce and measuring just 8mm in diameter, the Britannia fortieth ounce coin is the smallest UK coin ever produced by The Royal Mint. 8mm…. that’s smaller than a drawing pin!


To put this minting triumph into context, many of us would consider the five pence coin to be ‘small’ coin – right? But with a diameter of 18.00mm it’s more than double the width of the Britannia fortieth-ounce, as we demonstrated with this photo we took when the 2014 version was launched.

5p & 40th

First launched last year, the popular coin returns in the Britannia 2015 range in both gold and silver. The nautical-themed design by Antony Dufort is intended to have a simple and elegant feel. Britannia is wearing her familiar Corinthian helmet and holding the trident, with a masted ship with billowing sails in the background. The obverse of the coins bears the new, fifth definitive portrait of The Queen, designed by Royal Mint engraver Jody Clark – who also designed the 2014 Britannia.

Each fine detail of the design has been reduced perfectly by state-of-the-art technology and even on the fortieth ounce coin, the design is crisp and finished to Proof standard – complete with frosting!


Both the 2014 and 2015 Britannia Fortieth Ounce Gold Proof Coins are available to buy individually on www.royalmint.com, while the silver coin is available as part of a set.

    Why is it necessary for these ‘rip off’ prices – you would never re-coup you investment

  • Steve

    The value of the gold at present value is £17. How collectable are these coins in order to recoup any investment value?

  • The same coin has been made in silver, but it is only available as part of the Six-Coin Silver Proof set. Here’s the link: http://www.royalmint.com/shop/The_Britannia_2015_Six_Coin_Silver_Proof_Set

    Neither a collectable,or an investment.
    You are losing more and more collectors every month.
    Prices are just becoming a very expensive rip-off.
    I am rapidly losing interest in modern issues,doubt I will be collecting for much longer.
