50 Pence - Charles III Patron Saints - St. Andrew; Coloured

The four patron saints series issued by Guernsey follows a well-established tradition of British Crown Dependencies producing commemorative fifty-pence pieces outside the Royal Mint's purview — Guernsey has held its own coinage rights since a formal ordinance of 1921. St. Andrew's association with Scotland is older than Scotland itself as a political entity, rooted in the cult of relics allegedly brought to Fife in the 8th century. The selective colour application here is a private mint technique, not a Royal Mint process.
