Colombia
The New Kingdom of Granada was a gold economy in the most literal sense. Until a mint was established at Santafé in the 1620s there were almost no locally struck coins, and people paid each other in gold dust and small nuggets from the placers of Antioquia, Popayán and later the Chocó, weighed out by the castellano or peso de oro of about 4.6 grams. Because purity varied with the mine, contracts always specified carats: the rough mine gold called oro corriente ran 12 to 13 carats, buen oro about 20, and the royal treasury kept its books in fine gold of 22.5 carats. This makes New Granadan sums unusually easy to read as metal, since the unit of account was itself a stated weight and fineness of gold. What survives is largely notarial — the protocol books in Tunja and Bogotá preserve the contracts, obligations, dowries, inventories and wills in which painters, gilders, sculptors and carpenters agreed their prices — and between the 1580s and the 1700s these cities supported a dense trade of painters whose fees were written down in ordinary legal language.
