Materials analysis sheds light on minting mystery of 1834 British sixpence

According to a report by Phys.org… A severely deformed 1834 British silver sixpence preserves physical evidence most consistent with an unusual minting anomaly, according to an IA STUDIO study published in npj Heritage Science. The coin was individually marked £8 in a mixed coin album at a flea market in Greater Manchester. The album was later acquired as a bulk lot, rather than the sixpence being purchased separately for £8. complete report is on link below.
