Adding year for KM# 6 Bangladesh coin

I found the following 5 Paisa coin of Bangladesh. The date of the coin is 1979. But in the catalog there are no date of 1979. While I tried to edit the date, it is mentioned that the date is complete. Would anybody can help me in identifying the correct KM of the coin. Photo of the coin is attached below.

 

1979 added in the list.
