A new set of Harry Potter 50p coins will feature the portraits of Queen Elizabeth II and the recently proclaimed King Charles III.

The coins, which are being created by the Royal Mint, will commemorate the 25th anniversary of the publication of Harry Potter and the Philosopher's Stone by JK Rowling in 1997.

The book, which was published by Bloomsbury Publishing, was the first in a series of stories detailing Harry Potter's life at the fictional wizarding school of Hogwarts.

The Royal Mint is expecting a high demand for the coins but has said the Harry Potter collection will be one of "a small number" that will have a change of portrait during the series.

When are the Harry Potter coins launching?

The first two coins in the series are to launch this year and will feature the portrait of Queen Elizabeth who passed away in September at her Scottish estate of Balmoral in Aberdeenshire.

The final two Harry Potter coins in the series will launch next year and feature the portrait of Charles III who was proclaimed King at his accession ceremony a month ago.

Who will feature on the first Harry Potter 50p coin?

While the current and former heads of state will feature on the coins, the first coin will primarily depict the character of Harry Potter.
