1. About the Sherlock Holmes 50p Coin
Release and Commemoration
The Sherlock Holmes 50p was issued by the Royal Mint in 2019 to mark the 160th anniversary of Sir Arthur Conan Doyle’s birth. As one of literature’s most iconic detectives, Sherlock Holmes remains a cultural giant, and this was the first UK coin ever dedicated specifically to him. With millions entering circulation, the coin quickly became a favourite among collectors and casual finders alike.
Coin Design Features
Designed by artist Stephen Raw, the coin offers something genuinely unique. Instead of a simple portrait, Raw envisioned Holmes in his classic silhouette—deerstalker hat on, curved pipe in hand, eyes locked onto a mystery only he can solve.
What makes the coin truly special is the tiny lettering arranged around Holmes. The text lists many of Conan Doyle’s famous story titles such as:
-
The Hound of the Baskervilles
-
A Study in Scarlet
-
The Sign of the Four
-
The Valley of Fear
-
The Speckled Band
The lettering is so small that many owners find themselves reaching for a magnifying glass—adding an intriguing detective-like charm.
The obverse side features the fifth portrait of Queen Elizabeth II, created by sculptor Jody Clark.

2. Mintage and Rarity
The Royal Mint issued 8,602,000 Sherlock Holmes 50p coins into circulation, which immediately places it among the more common commemorative 50p coins.
Even though collectors enjoy its design, the coin holds a Scarcity Index rating of 1, making it officially classified as common. It sits around 65th position on the overall scarcity index—well behind more sought-after coins like:
-
2009 Kew Gardens 50p (210,000 minted)
-
Olympic 50p series (various rarities)
-
Beatrix Potter character coins, some of which are significantly scarcer
So why is it still collectible? Because demand isn’t built solely on rarity—design, theme, and cultural significance matter tremendously, and Sherlock Holmes remains a figure people love to collect.
