In 1995 and 1999, Rupees Five coins were issued into circulation as commemorative coins.

This 3.1mm thick coin is similer in design to the British pound and still in regular circulation. However even at the time of first issue of this coin in 1984 it's value was only 1/7th and by late 2004 deflated to under 1/40th of a British pound. A high security coin now worth under a dime. It is the highest definitive denomination of coin in regular circulation.

According to a statement reported to have been made at the Press Conference on 2005 December 14th some five rupee coins are smuggled to London where vending machines can be fooled into accepting it as a one pound coin. The British Pound is 9.5 grams and 22.5 mm in diameter. The Lankan Rs5 coin is 23.5 mm in diameter and was of the same weight, and thickness which is probably why the newer Brass plated Steel coin is about 13% thinner and at 7.7 grams is 19% lighter. That is probably sufficiently lighter for coin machines to identify it as not a pound. If the Rs5/- coin was shaved to the diameter of the British Pound it is only 8.33% lighter

The coin was scaned at 300 dpi and the edge at 600 dpi. The images are displayed at 200 dpi.

Need to recheck the Alloy. Sallay and the Fax from CBSL gives it as Nickel Brass but Krause lists it as Aluminium Bronze.
