Honoré II secured formal recognition of Monegasque sovereignty from Louis XIII in 1641 through the Treaty of Péronne, which ended Spanish suzerainty and placed Monaco under French protection. The coinage that followed — including this thaler — was among the first issued under that newly confirmed independent authority, making it one of the earliest expressions of Monaco as a sovereign principality rather than a Spanish client state.
The 28-sol denomination places it within the complex tariffing system of mid-17th-century French-sphere currencies, where foreign silver was formally valued against French monetary standards by royal ordinance.
