ONE PENNY (1933) - King George V (1910-1936)
The exact number has never been determined, but it is thought that 7 pennies were struck - the 7th is not traceable at the moment. (1) British Museum, (2) Royal Mint Museum, (3) Norweb Private Collection in the USA, (4) University of London [as part of a 1933-dated set placed under the foundation stone], (5) Private collection [1933-dated set was unearthed in September 1970 from under the foundation stone of St. Mary's, Hawksworth Wood, Kirkstall, Leeds, in the presence of five senior Church officials, and taken to a local branch of the National Westminster Bank for safe keeping, where it remained until a decision was taken to sell the coins and use the funds raised for restoration purposes], but it was later stolen circa 2003, (6) Whereabouts not known (stolen in 1970); formerly under the foundation stone of the Church of St Cross, Middleton, near Leeds. The theft of this set was discovered in August 1970, after which steps were taken to safeguard the other set in the custody of the diocese of Ripon (see No.5 above) and (7) Private collection (since 1982) - this coin is understood to have changed hands more than once in commerce between 1972 and 1982.

THREE PENCE (1937) - King Edward VIII (January - December 1936)
A small number of these coins were produced for experimental purposes and a few did get into circulation. No coins of Edward VIII were issued for currency within the United Kingdom bearing his name and portrait. The Royal Mint had commenced work on a new coinage prior to the Abdication, and various patterns were made.

Possibly unique. All specimens were melted down with only one, possibly two, getting out of the Royal Mint.

HALF CROWN (1952) - King George VI (1936-1952)
It was found by a London man in his loose change. The George VI coin was minted in 1952 - the year the King died - and should not have been issued. No half-crowns were officially sent out that year. The half-crown has been examined by Royal Mint experts who have issued a certificate in 1967 to say that it is genuine. The Royal Mint has no record of how many were made and apart from coins fraudulently altered from other dates, they have only ever seen one piece. The coins was probably sent out from the Royal Mint accidentally - perhaps in a batch of 1951 half-crowns. careful inquiries have so failed to make clear how the half-crown was struck. Up to date, 1952 was the only gap in the issue of half-crowns in every year since 1874. Now the gap has been filled by this one piece.

ONE PENNY (1954) - Queen Elizabeth II (1952-)
There was a small production run of something like 2000 to test the dies. These coins were melted down immediately afterwards but one at least is known to have escaped the melting pot and was sold a little while later to a London coin dealer. Whether any others survived is unknown but so far it seems that only one specimen has come to light.
