Colombia's 1857–1858 gold coinage was struck under the Granadine Confederation, the short-lived federal republic that replaced Nueva Granada and would itself be superseded by the United States of Colombia in 1863. The confederation's brief existence — just four years — means the window for this issue was narrow, and total output across both years was modest.
The .900 fineness aligns with the French metric standard Colombia adopted mid-century, part of a broader effort to make its gold coinage acceptable in international trade, particularly with European creditors. Bogotá remained the sole mint for this type.
