Common questions
How much is the 1825 1 Crown - George IV Uniface Pattern worth?
The 1825 1 Crown - George IV Uniface Pattern has a price in one grade on MyCoinage so far: £9,100 in PR-65, the median of its verified sales.
What is the 1825 George IV uniface crown?
A trial striking of only the obverse of the new crown: the bare head of George IV with the date 1825, on a flan with a blank back. It was struck in Barton's metal, a gilded copper, and was never issued as money.
Why was a uniface crown made?
It tested the new obverse die on its own. Heritage describes these 1825 pieces as the first trials struck with the new Chantrey-based portrait of George IV, ahead of the proof set of 1826.
Is the uniface crown made of gold?
No. Heritage describes Barton's metal as gold-electrolysed copper, and the Royal Mint Museum records its George IV uniface crown in the same material. The piece is copper with a gold surface, not a gold coin.
How do I identify the 1825 1 Crown - George IV Uniface Pattern?
Check the diameter 38.6mm and the metal (gold plated copper) against the specification table on this page. The reverse design is described above.
History and design
In the mid-1820s the Mint replaced Benedetto Pistrucci's laureate portrait of George IV, which the King disliked, with a bare head based on a bust by the sculptor Francis Chantrey. Pistrucci refused to copy another artist's work, and the new portraits were engraved by William Wyon and Jean Baptiste Merlen.
This piece is a uniface trial of the new crown obverse, dated 1825, struck on one side only. Heritage Auctions, describing a cased set of six such trials (obverse and reverse of the crown, double sovereign and sovereign), calls them the first trials struck with the Chantrey-style portrait and links them to the proof set released the following year. The crown obverse in that set is catalogued as ESC 2333.
The single struck side shows the bare head of the King facing left with the date 1825 below, the portrait used on the later proof crowns, which read GEORGIUS IV DEI GRATIA. The Royal Mint Museum notes that Wyon's portraits of George IV were based on Chantrey's busts and so were not entirely his own work.
The piece is in Barton's metal, which Heritage describes as gold-electrolysed copper, so it has the colour of gold without being gold. The back is blank.
Collecting notes
No number struck is recorded, and Heritage believes the set it sold, still in its original red leather case, was a personal gift from someone at the Mint. Heritage notes contact marks and planchet flaws on the set it sold, which it treats as part of the experimental character of these pieces. A gilt surface on copper wears through easily, so check the high points of the hair and cheek for copper showing.
The matching uniface of the reverse is listed separately as the reverse uniface crown. The finished design appears on the proof crown of 1826.
