This is a unique pair of 1825 English Gold Sovereign die trials. The obverse design depicts William Wyon's Bare Head of George IV to left, legends around, date below and a blank reverse. The reverse design depicts crown and draped arms surrounded by legend with a blank obverse.
Both of these die trials are in choice brilliant proof condition and have an attractive gold color. This is the only pair of 1825 Sovereign die trials known and are not recorded in any reference books. These are missing from all major English gold collections.
The composition is copper plated with a heavy layer of gold since these are Barton's metal specimens. This die trial pair is a significant rarity and is now being offered for the first time. They were purchased from a major collection consisting of English proof and mint state Sovereigns and Sovereign Patterns.
The only other uniface gold die trial of George IV is a 5 Pound piece which was auctioned by American Numismatic Rarities when they sold the Eliasberg Collection. It was valued in their catalog between $25,000 - $40,000.
