GALL stood for Galle, a city on the southwest coast of Ceylon. Given Portuguese activity on the island, coinage from fellow colonies were imported for use. Some issues, such as the present piece, were specifically struck for exporting to Ceylon while others made their way to the island through commerce. Following the Dutch East India's successful campaign to drive out the Portuguese from the island in the mid-17th century (Galle 1640, Colombo 1656 and Jaffna 1658), coinage was subsequently countermarked for the new authority. The prevailing rate for Indo-Portuguese coins then in circulation was 5, 6 and 10 Stivers and were to be countermarked with the cities monogram. Due to large amounts of counterfeits in circulation all coins were inspected by a competent goldsmith and if found to genuine were countermarked.
