Royal Mint to auction rare samples, including Kew Gardens 50p

A trial piece is one of the first samples struck using a new die, and is carefully inspected by coin makers at The Royal Mint to ensure it meets their exacting standards.

The trial pieces are then stored for posterity and the design is officially approved by Her Majesty the Queen before coin striking can begin.

To ensure authenticity, each die trial piece bears a hallmark stating the quality of the metal and a unique latent security feature – designed by The Royal Mint’s Chief Engraver, Gordon Summers.

A die trial piece is one of the first coins struck and sets the standard for all coins issued.  They are used to prove tooling, and clarity of design and detail for proof coins, ensuring they are accurate enough for a perfect strike to be used in production.

These pieces do not form part of the standard issue limit and have not been put on sale before by The Royal Mint.

Your chance to buy trial pieces

On 26 September, The Royal Mint will offer sixty rare examples of trial pieces to the public for the first time following growing demand from collectors. 
 
Rebecca Morgan, Director of Collector Services at The Royal Mint, said:

“Each year The Royal Mint introduces a range of original new coin designs celebrating British milestones, anniversaries and themes. Each of these designs requires a trial to ensure the design meets our exacting standards, and results in a handful of trial pieces.
 
“This month we are delighted to offer a sample of our trial pieces at auction for the first time. Each of the trial pieces has played an integral role in creating the final coin, and offer collectors the chance to own a part of numismatic history.
 
“Interest in trial pieces has grown significantly over recent years, as customers increasingly seek out exclusive and rare items for their collections. Many customers will treasures the trial pieces as part of a collection or even investments – so we have added a security feature to safeguard their provenance.”
