In accordance to a resolution of the Galle Council dated 1655 April 19th, Indo-Portuguese coins current at rate of 10, 6, and 5 stuivers were countermarked with a round stamp representing a monogram composed of letters GALL after they were tested by competent goldsmiths and declared genuine. A large number of counterfeits were in circulation at the time. Codrington (IX:5,p.109) states the double tanga was 10 Stuivers and the 6 Stuivers seems to be the heavier Malacca Type.

Illustrated in Mitchiner (2144) 164x, and (2145) of 1642.
Catalog of the Colombo Museum No 86 -- 4.22 grams.
Illustrated in Scholten (1265) who lists it as extremely rare (RRR).
