The Royal Mint is certainly on the case when it comes to making one, with its new Sherlock Holmes range of 50p coins ranging in price from a modest £10 for a brilliant uncirculated coin (translation: shiny) all the way up to a £795 Gold proof coin.
It's the first time that the literary character has been featured on a coin and it's being rolled out to celebrate 160 years since the birth of Sherlock's creator, Sir Arthur Conan Doyle, born May 22, 1859. The silhouette of the detective is surrounded by tiny text that only the eagle-eyed (or those with a magnifying app) will be able to decipher as the names of Holmes' most famous cases
"Growing up in London in the 1950s and 1960s, my father would often take a short detour in the family car to drive down Baker Street to see where Sherlock Holmes had lived," said the coin's designer, Stephen Raw, via Microsoft News. "I love all the stories - in my design for the coin I have listed the most popular of those adventures but by necessity have kept the words very small.
"I hope it will encourage the 'inner detective' in those who are intrigued by the coin. Naturally, the only way to solve 'the mystery of the text' is by using that essential piece of equipment always carried by the intrepid sleuth: a magnifying glass."
The coin joins the rank of other 50ps that collectors are willing to pay ludicrous amounts of money for, like the Peter Rabbit coin that was one of four Beatrix Potter-themed 50p pieces released into the wild back in 2016. And let's not forget the "incredibly rare" Kew Gardens 50p Coin that was doing the rounds in 2014 that would've fetched £24 at the time. The same coin is up on eBay right now for £370.
"We are all huge fans of Arthur Conan Doyle at the Royal Mint, which makes us all very happy to honour him with his own coin," said Nicola Howell, director of the consumer division at the Royal Mint.
From the three limited edition runs of the coin alone, which includes 6,000 silver proof coins priced at £55, 2,500 silver proof piedfort coins at £95 each, and 400 gold proof coins with a £795 price tag, the Royal Mint will bring in £885,000. The stock of the £10 option is unknown.
The Sherlock Holmes coins will be available to the masses in a few months, but no date has been specified just yet.
