Pakistani paisa

The breakdown of the pre-decimal currency system in Pakistan needs correction. It's given as:

3 pies = 1 pice • 4 pices= 1 anna • 16 annas = 1 rupee

As seen on various coins, both "pice" and "paisa" are used as singular and plural, but there is no "pices". Not sure if the same problem is present in the listings for India as well. Admin, can you fix that?
