Gulden Bronze trial

Louis Bonaparte, installed as King of Holland by his brother Napoleon in 1806, spent much of his short reign attempting to construct a functioning Dutch monetary system largely from scratch. The bronze trial of 1808 reflects that experimental phase — multiple compositions and module sizes were tested before the definitive silver gulden coinage was settled. Louis's genuine effort to govern Holland as a Dutchman rather than a French satellite eventually irritated Napoleon enough to trigger the kingdom's annexation in 1810, leaving many of these trial and pattern pieces as the only physical record of monetary ambitions that never fully materialized.
