Most Lankan commemorative coins from 1995 to 2001 were issued with respect to 50th anniversaries celebrations. Other than the two coins for the Cricket World Cup, 11 of the 13 coins issued in the seven years between 1995 and 2001 from Sri Lanka have been for 50th Anniversary commemoratives. The issues in these 7 years almost equal to the 14 commemoratives issued in Sri Lanka in the previous 46 years since independence. An sevenfold increase in the rate of commemorative coins issued by the Central Bank of Sri Lanka.
