Codrington (VIII-21:III,p.100) lists it among silver coins struck for Ceylon as the third series Saint type of 1650-1653.
They were minted in Goa with dates 1641, 1642, 1643 and 1649.
The circulation of the São João Tanga was forbidden in Goa in 1650 when the Cross of Christ coinage was introduced.
Minting was however continued in Goa with dates 1650, 1651 1652, 1653 and 1655 for circulation only in Ceilão. Jaffna, the last foothold of the Portuguese fell into the hands of the Dutch in 1658.

This coin struck at Goa, circulated largely on the island of Ceylon, with many other Indo-Portuguese coins
Robert Knox in his book History of Ceylon mentions this coin: "Of money they have but three sorts that passeth for coin in the King's dominions: the one that was coined by the Portugal; the King's arms on one side, and the image of a friar on the other, and by the Chingulays called tangom massa."

In Grogan section on Ceylon the double Tanga is illustrated
(1326) of I6S0 -- 19/20 mm ; 4.27 grams and
(1327) of I6Si -- 20/19 mm ; 4.16 grams.
(1328) of I6Si -- 20/19 mm ; 4.16 grams.
(1329) of I6S2 -- 19/18.5 mm ; 4.20 grams.

The Krause listing of extra year 1656 must be from a similar issue struck for Diu with the initial Å D, which are known for the dates 1654, 1655 and 1656. Mitchiner (#2167) lists the Diu double Tanga with mintmark Å D countermarked in Jaffna with a R.
