In 1898, the Goldsmiths' Company became aware that fake silverware was being traded by Reuben Lyon of Holborn. When police raided his premises, over 300 pieces were seized and Lyon was fined £3000.
On April 11 the following year at The Old Bailey, London, Charles Twinam, a silversmith of Latham Street, Holloway was found guilty of supplying the fakes and sentenced to five years' penal servitude.
Police had raided his house to find a large collection of punches with the initials of various 18th century silversmiths, including George Smith, John Manby and William Shaw amongst others, along with items of modern silver punched with these marks. Despite the evidence, Twinam pleaded not guilty and claimed that the parcel of punches had been left with him by a "Devonshire man" 14 years earlier.
Following the trial, the confiscated goods were melted down and the resulting bullion used to cover costs. However, some of these high-quality fakes may still be undiscovered today.
