The Mint says about the set:
As Her Majesty The Queens becomes the first British monarch to celebrate a Platinum Jubilee, this two-coin set honours a monarch like no other. Throughout her reign, the portraits that appear on the coins we use every day have charted Her Majesty’s journey from a newly crowned queen to an experienced and record-breaking monarch.
One of the coins features the commemorative Platinum Jubilee portrait of Her Majesty The Queen created especially for the occasion. Created by Jody Clark, The Queen’s fifth definitive coinage portrait has appeared on all UK coins that have entered circulation since 2015. For 2022, the experienced coinage artist John Bergdahl designed a Platinum Jubilee portrait in celebration of this special milestone in Queen Elizabeth II’s reign.
Struck in sterling silver and finished to Proof standard, both coins feature a bold, typographic reverse design by the design agency Osborne Ross. Presented together in a case, a booklet exploring the definitive coinage portraits of Her Majesty’s reign accompanies the coins.
