1 Thaler - Louis I

Monaco's 1668 thaler is a product of Louis I's early reign — he had assumed the lordship just a year prior following the death of Honoré II, who had spent decades maneuvering the principality away from Spanish suzerainty and toward French protection. The thaler denomination itself was something of an anomaly for Monaco, reflecting the commercial currency conventions of broader European trade rather than any indigenous monetary tradition.

The Gadoury reference MC79 places this among the rarest Monaco silver issues of the seventeenth century. Surviving examples are sparse enough that auction appearances routinely draw significant specialist interest regardless of grade.
