Recycled Silver Sixpences Make History at the Trial of the Pyx

Tuesday 11 February 2025: A centuries-old tradition met modern sustainability as The Royal Mint submitted its latest coinage for testing at the 776-year-old Trial of the Pyx—one of the UK’s most historic judicial ceremonies. Held at Goldsmiths’ Hall in the City of London since 1871, the Trial ensures the nation’s coinage meets strict standards of precision, accuracy, and craftsmanship.

This year’s Trial featured a groundbreaking submission: sixpences made from silver recovered from expired medical and industrial X-ray films. In a historic first, these innovative coins—released last year as part of The Royal Mint’s commitment to sustainability—will now undergo rigorous testing by the London Assay Office.

The recycled silver sixpences were originally issued to mark the revival of ‘Stir Up Sunday,’ a Victorian tradition where families would add a silver sixpence to their Christmas pudding mix for good luck. Their inclusion in the Trial of the Pyx signals not only their significance in British numismatics but also the ongoing efforts to merge heritage with sustainability.

In total, The Royal Mint has submitted 6,432 coins to this year’s Trial, including gold bullion Sovereigns, 24ct Britannias, and a variety of collectable designs. Among the standout pieces are commemorative coins celebrating the 20th anniversary of The Gruffalo’s Child, additions to the ever-popular Harry Potter and Star Wars collections, and a stunning trio of coins inspired by the legend of Robin Hood.

As per tradition, the coins will be meticulously examined by an independent jury composed of members of the Goldsmiths’ Company—a role they have upheld since 1327. The process involves expert craftsmanship assessment as well as scientific analysis conducted by the London Assay Office. The Trial is overseen by the King’s Remembrancer, Senior Master Jeremy David Cook of the King’s Bench Division of the High Court, who will later deliver the official verdict in May.

What is the Trial of the Pyx?

The Trial of the Pyx is one of the oldest judicial processes in the United Kingdom, dating back to at least 1248. Its primary purpose is to ensure that coins produced by The Royal Mint meet the required standards of weight, composition, and quality. The term “Pyx” refers to the chests in which the coins are stored before testing. The trial is conducted at Goldsmiths’ Hall in London, where a selection of newly minted coins is scrutinised by an independent jury, composed of members of the Goldsmiths’ Company. The process involves both visual inspection and scientific analysis by the London Assay Office. The King’s Remembrancer, a senior judge, oversees the proceedings and delivers the final verdict once testing is complete.

With tradition and sustainability now working hand in hand, the legacy of British coinage continues to evolve in remarkable ways.

 Stir-up Sunday

Stir-up Sunday falls on the last Sunday before the Christian Advent begins – that’s 4 weeks before Christmas Day. The term ‘Stir-up Sunday’ originates from the Anglican Book of Common Prayer: ‘Stir up, we beseech thee, O Lord, the wills of thy faithful people.’

So, why is the Christmas pudding whipped up long before the big day? Well, the idea is that enough time will pass for the pudding to mature and for the spices to infuse – yummy!

Making a Christmas pudding can be hard work, and during the Victorian era the whole family would get involved. While stirring the mixture of fruit, flour, brandy and spices, each family member would make a wish.

Some families threw a piece of silver – traditionally a sixpence – into the mix, which is thought to bring luck and wealth to whoever received it on Christmas Day.

Perhaps this is something you’d like to try with your family this year. Let us know in the comments if you’ll be participating in Stir-up Sunday and what you’d wish for.
