Soho Mint 1798 copper guinea trials

[Deeman]

Soho trials by Conrad Heinrich Küchler. The obverse design is a laureate, draped bust of the king facing right inside a wide rim having an incuse circumscription translating to 'George III, by the Grace of God'. The initials CHK are on the lower drapery. The reverse design is a crowned spade-shaped Shield of Arms. An abbreviated incuse circumscription around the shield translates to 'King of Great Britain, France and Ireland, Defender of the Faith, Duke of Brunswick and Lüneburg, High Treasurer and Elector of the Holy Roman Empire', with 1798 in the gap at the bottom of the shield. The abbreviated Latin in full reads Magnae Britanniae Franciae ET Hiberniae Rex Fidei Defensor Brun ET Lünebergen Dux Sacri Romani Imperii Archi-Thesaurarius ET Elector.

1798 Küchler trial gilt copper guinea, en médaille.




1791 and 98 double-reverse bronzed copper guinea trial mule. Struck en médaille on thick flan weighing 7.5g.
Each side has a similar design but vary in both crown and shield detail, and size of lettering in the circumscriptions.
The 1798 side is attributed to Küchler, but as he didn't start work for the Soho Mint until 1793 there is a question mark as to the 1791 side's attribution.

Soho Mint gold pattern guinea set amid a mirror field offset by broad and heavily frosted borders.
The attribution must be to Jean Pierre Droz, which answers the question in the previous post. He returned to the Paris Mint in 1791.
