The pataca was first introduced in Portuguese Macau and Portuguese Timor in the year 1894, but only as a unit of account for the silver Mexican dollar coins that circulated widely in the region at that time. In 1894, Macau and Portuguese Timor constituted one single administrative entity, but in 1896 Portuguese Timor became autonomous from Macau. In those days there was no single currency in circulation in Macau and East Timor, and trade was dominated by the silver dollar coins, not only of Mexico, but also of China, as well as the British silver trade dollars that were minted for use in Hong Kong and the Straits Settlements. In East Timor, the 2½ Gulden coin of the neighbouring Netherlands East Indies also corresponded to a silver dollar. In 1901 in Macau, it was decided to create a purely local currency, and the authorities granted the Banco Nacional Ultramarino exclusive rights to print legal tender banknotes. These pataca banknotes were launched in 1906 at a sterling value of 2s 4d (2 shillings and 4 pence) — the same as the new Straits dollar that was issued in that same year. As in the Straits Settlements, all foreign coinage was outlawed, with the intention that the new currencies should establish their own market values. The Chinese were suspicious of these paper patacas, being accustomed to using silver for barter, and so the paper patacas always circulated at a discount in relation to the silver dollar coins. These Macau banknotes also circulated in East Timor, but in 1912 they were supplemented by local Timor issues for the first time. While the pataca continued at a discount to the silver dollars that were used in silver standard countries such as China and Hong Kong, the Straits dollar was pegged to sterling in a gold exchange standard, so the two currencies then floated apart. In 1935, when China and Hong Kong abandoned the silver standard, the pataca was pegged to the Portuguese escudo at a rate of 1 pataca = 5.5 escudos, making it equivalent to the British shilling (since £1 was then equivalent to 110 escudos) and putting it officially at a 3d sterling discount in relation to the Hong Kong unit, and at a 1s 4d discount in relation to the Straits dollar.
