1987-1990 Currency Notes
Historical and Development

In 1986 the Central Bank of Ceylon changed it's name in English to Central Bank of Sri Lanka, a name it had used in Sinhala on Currency since 1956. In 1984 Bradbury Wilkinson opened a Joint Venture in Biyagama export promotion Zone to print Currency for Sri Lanka and the World. Bradbury Wilkinson was aquired by compititor Thomas De La Rue in 1986 but the old name was retained as name of Printer in Sri Lanka Currency Notes till 1991 issue.
However under new management the printer issued Replacement Notes with R prefix as it had with V and W in 1970.

The UV printing consists in Front of Signature, Date and Serial Numbers, and on right outlines of large Flag Lion with Sword in raised right paw, and large numeric denomination highlighting design at center.

Visually the currency notes of each denomination are of same type. However under Ultra Violet illumination there are two color types. The UV-Printing on back is predominantly always in Green. However the UV-printing in front of Notes issued with date 1987-01-01 and 1988-02-01 is in Orange or Yellow, while the later dates 1988-11-21 1989-02-21 and 1990-04-05 is in Green. Only the Rs 10, Rs 100, Rs 500 and Rs 1000 denominatins were issued with the first two dates.
