Prestigious Silver Piedfort: Code-breaking UK Alan Turing 50p

Own the extremely limited edition Silver Piedfort 50p coin released by The Royal Mint, honouring mathematician, philosopher and scientist, Alan Turing!

The coin design itself features three hidden codes, but what's really intriguing is the edition limit...

Double the weight AND thickness

Struck to Piedfort quality, each coin has been struck using a double thickness Sterling Silver blank, meaning it is double the weight as a standard Silver 50p. The edition limit of this 50p coin is  also half that of the standard silver specification, making it much scarcer. 

In fact, just 1,500 have been produced by The Royal Mint! When you consider the SOLD-OUT Stephen Hawking Silver Piedfort 50p had an edition limit of 2,500, demand will likely outdo supply. 

What's more, the design itself features three elements worthy of a code-breaking expert like Turing…

Code 1. GEARS.GRIN.THAN Every 3-square-meter of the world has been given a unique combination of three words. Go to ‘whatthreewords’ to find out where Turing studied at University…

Code 2. ‘ONLY A FORETASTE OF WHAT IS TO COME’ Turing’s quote in The Times, June 1949

Code 3. Matt Dent and Christian Davies The coin designers initial
