is of Indian origin and was first minted in India
during the reign of Mughal Emperor Sher Shah (1540-1545).
It had a weight of 11.3 grams of sterling silver.
There was a Ceylon rupee minted to the Surat
standard by the Dutch in Colombo between 1784
and 1789. Since under 250,000 of them were known
to have been struck, and most of them would have
been melted, very few specimens are known to exist
and are extremely rare.
Although Ceylon silver coins of 50 cents, 25
cents and 10 cents circulated for 50 years from
1892 to 1942, the silver rupees used in Sri Lanka
were of Indian origin. The Indian silver rupee
was made legal tender in 1870, although it had
been used in circulation in Ceylon since 1825.
There have been many Lankan commemorative coin
issues since 1957, but the one-rupee denomination
was only once minted in silver.
These were not the first time that Ceylon copper
coins were minted in silver and gold. On the request
of private individuals, provided the dies were
available, the Indian mints did unusual "proof
restrike" in silver and gold of the copper
coins on payment of prescribed fees and bullion
A number of these precious metal restrikes are
listed in coin catalogues for many of the Victorian
and Edward VII Ceylon coppers.
