The new design revenue stamps were released on February 1, 2009. Five denominations were issued at that time i.e. RM5, RM10, RM50, RM100 and RM250. So, the smallest denomination at the initial release was RM5. However, RM1 revenue stamp is needed for some documents due to change of revenue policy (I am not sure for what kind of documents), therefore the Inland Revenue Department has decided to release RM1 revenue stamp. The new denominaton RM1 was released in August 2009. As the other denominations, the RM1 revenue stamp has similar design and is also printed in sheetlet of 20.
