Currency in Colombia denotes the ingots, coins, and banknotes that have been used in Colombia since 1622. It was in that year, under a licence purchased from King Philip III of Spain, that Alonso Turrillo de Yebra established a mint at Santa Fe de Bogotá and a branch mint at Cartagena de las Indias, where gold cobs were produced as part of Colombia's first currency. Silver milled coins date from 1627. In 1831, Gran Colombia dissolved into Venezuela and New Granada. In 1836, in New Granada, new monetary laws were passed, to standardise the money produced in the country. From 1861 to 1862, due to financial instability, the United States of New Granada accepted British currency, the name of the country becoming the United States of Colombia in 1862. In 1880, Colombia pegged the peso to the gold standard due to the falling price of silver. In 1886, the paper peso was introduced. In 1931, Colombia abandoned the gold standard and switched to the current form of the peso.
