Common questions
How much is the 1963 Half Decimal Penny Uniface Pattern worth?
No verified sale of the 1963 Half Decimal Penny Uniface Pattern has been logged on MyCoinage yet.
What is the 1963 decimal halfpenny uniface?
It is a one-sided bronze trial piece struck at the Royal Mint in 1963 during secret preparations for a decimal coinage. It shows Christopher Ironside's Welsh dragon with the value below and has a blank back. It was never issued as coin.
Is the 1963 halfpenny pattern the same as the 1971 halfpenny?
No. The issued ½p carried Ironside's later work, chosen after the open competition announced in November 1966 and unveiled in February 1968. The 1963 piece is an earlier trial reading DECIMAL ½ PENNY 1963, with a Welsh dragon and a blank back.
How can I tell a uniface from a two-sided 1963 pattern?
The uniface has a blank back. The Royal Mint Museum also holds two-sided 1963 decimal halfpenny patterns that pair the reverse with Arnold Machin's crowned portrait reading ELIZABETH.II D.G.REGINA.F.D, weighing about 1.73g against roughly 1.80g to 1.86g for the unifaces.
Is the decimal halfpenny pattern legal tender?
No. It is a trial piece made for the Royal Mint's own design work and was never issued, so it has no legal tender status or face value.
How do I identify the 1963 Half Decimal Penny Uniface Pattern?

History and design
This piece is a uniface trial, struck in bronze at the Royal Mint on Tower Hill in 1963 with a design on one side and a plain back. It comes from the Mint's private preparations for a decimal coinage, which the Royal Mint says began in 1962 with no government decision yet made, and which were kept secret from 1962 to 1968.
The decimal halfpenny was a real denomination in the end, but not with this design. In 1966 the Chancellor announced decimalisation and the government insisted on an open competition for the designs, announced in November 1966. Ironside entered again, and the Royal Mint Museum records that his new series for the ½p, 1p, 2p, 5p and 10p was unveiled in February 1968. No figure has been published for how many of the 1963 trials were struck.
The Royal Collection describes the design as a Welsh dragon with the value below, reading DECIMAL ½ PENNY 1963. The designer was Christopher Ironside, then a teacher of life drawing at the Royal College of Art, who had joined the combined Royal College of Art and Royal Designers for Industry team that won the Mint's first, private competition.
The back is blank and the edge is plain. The Royal Mint Museum's unifaces weigh between 1.80g and 1.86g, and the Royal Collection gives a diameter of 1.7 cm. The Museum also holds two-sided 1963 patterns that pair this kind of halfpenny reverse with Arnold Machin's crowned portrait of the Queen, which the Museum says had been prepared with decimal coinage in mind.
Varieties and errors
The Royal Mint Museum's records separate the halfpenny unifaces into two groups: pieces described only as having a plain back, at about 1.85g, and pieces marked as a modified design, at about 1.80g. The records do not describe what was changed.
Collecting notes
Known examples are mostly in institutional hands, at the Royal Mint Museum and the Royal Collection. On any piece offered, confirm that the back is blank rather than carrying a portrait, and weigh it: the two-sided Machin patterns are lighter, at about 1.73g. The legend should read DECIMAL ½ PENNY 1963.
The piece was never currency and is not legal tender. It sits in a small group of 1963 Ironside trials that also includes the quarter decimal penny uniface in aluminium.
