The provisional coinage of Tarragona, Spain, in 1809, refers to a series of coins minted locally during a period of political and military upheaval in Spain, particularly during the Peninsular War and the French occupation. The term "duro" typically refers to a silver coin, and during times of crisis and occupation, various Spanish cities issued their own coinage as a form of resistance or to maintain economic stability.

During the Napoleonic era, the French invaded Spain, leading to a struggle for independence known as the Peninsular War (1808–1814). As a response to the disruption caused by the war and the French occupation, some Spanish cities issued their own coins independently of the central government.

The provisional coins of Tarragona from 1809 could have various designs, symbols, and inscriptions reflecting the local sentiments and resistance against the French. These coins were often minted hastily and may bear the hallmarks of the challenging times they were produced in.

If you have a specific coin from the provisional coinage of Tarragona in 1809, its historical significance, rarity, and value will depend on factors such as the condition of the coin, the specific design, and demand among collectors of Spanish or Napoleonic-era coinage.
