Frequently Asked Questions
Why is the British 1933 Penny so famous?
In 1933, British commercial banks and post offices had an immense surplus of bronze pennies. Consequently, the Royal Mint did not produce any pennies for general circulation. Only about seven specimen coins were struck: three for foundation stone time capsules in new buildings, three for national museum archives, and one for private presentation.
How many genuine 1933 British pennies exist?
Numismatic records confirm that only seven genuine regular-die 1933 pennies were struck by the Royal Mint. In addition, four pattern trial pennies designed by French artist André Lavrillier were struck, bringing the total known population to approximately eleven specimens.
Where are the known 1933 pennies located today?
Three specimens are in permanent museum collections: the British Museum and the Royal Mint Museum. Three were buried under church foundation stones (including St. Mary's Church in Hawksworth and the Church of St. Cross in Middleton, Leeds), though one foundation coin was stolen by thieves in 1970. One regular proof specimen and the Lavrillier patterns are held in elite private collections.
Could a genuine 1933 penny be found in pocket change or grandma's jar?
Virtually impossible. Because no 1933 pennies were ever released into general circulation, any '1933 penny' found in old change or flea markets is almost guaranteed to be a common 1930, 1934, or 1935 penny with the last digit modified, or a modern novelty replica.
How can you detect an altered 1933 penny?
Counterfeiters carve a 1934 or 1935 penny into a 1933. Under magnification, look for: 1. Disrupted patina or copper discoloration around the date. 2. A '3' that is too thin, tilted, or has unequal serif loops. 3. Tool marks and metal removal depressions in the field beneath the digit.
What is the André Lavrillier 1933 pattern penny?
André Lavrillier was a French medalist who prepared an alternative, highly refined bust of King George V for the Royal Mint in 1933. Struck in tiny trial quantities, one of these Lavrillier pattern pennies sold at auction for over £100,000 in London.
How much is a genuine 1933 British penny worth?
Because only one or two specimens can ever appear on the private market, a genuine 1933 British penny commands between £120,000 and £200,000+ ($150,000 to $250,000 USD) when offered at major international auctions.
