1 Guinea - George III Pattern

This 1782 pattern was produced as part of ongoing attempts to address the chronic shortage of reliable gold coinage in Britain, a problem that had plagued commerce for decades due to widespread clipping and counterfeiting of circulating guineas. Pattern pieces in copper allowed the Royal Mint to trial proposed designs and gauge official reaction without committing gold bullion to a full production run.

The KM#PnA59 attribution places it among a cluster of experimental strikings from the early 1780s that preceded Matthew Boulton's later mechanized coinage reforms at Soho Mint.
