People living in the West Yorkshire city of Bradford have been advised to examine their loose change for a particularly scarce 50p piece featuring an Olympic swimming theme.
The coin, issued to commemorate the 2012 London Games, was characterised by the Royal Mint as an exceptional specimen.
The design showcases a competitive swimmer captured mid-stroke.
A small batch of these coins was distributed into general circulation before the official design was revised, and specialists in numismatics suggest additional examples may still be passing through everyday transactions.
One example of the piece changed hands on the internet auction platform eBay for a sum of £4,000, representing a value approximately 8,000 times greater than its monetary denomination.
This particular sale, completed during the previous year, generated considerable interest with no fewer than 28 separate offers placed by prospective buyers.
According to information from the Mint, the original design was the work of creator Jonathan Olliffe.
The image portrays a swimmer in motion, with flowing linear patterns etched into the coin’s surface to evoke the appearance of water.
In the initial, scarcer version of the coin, these wave patterns extended across the swimmer’s facial features.
Following the release, modifications were implemented to render the face more discernible, though not before the earlier design had already been dispersed into public hands.
A particularly intriguing aspect of this collectable piece lies in the uncertainty surrounding how many specimens of the original design entered general circulation prior to the alterations, with officials confirming only that the quantity remains exceptionally low.
The sale mentioned attracted 28 competing offers before the hammer fell at £4,000, prompting enthusiasts nationwide to begin inspecting their pocket change for potential discoveries.
