Cartagena declared its independence from Spain in 1811 and held Royalist forces at bay for four years. Cartagena was eventually retaken by the Royalists’ in 1815; though Spain would ultimately lose Columbia to independence in 1820. During the siege the city was deprived of many resources, including an adequate minting facility. Republican forces issued a minuscule amount of crude coinage out of necessity during the siege by the Royalist Army. This is one of those coins.
This coin exhibits moderate corrosion, but is still a rare and important coin of the South American revolution against Imperial Spain.
