Great, thanks Parimal - I'd have had some search without your help.

Now, how do I tell exactly which exact mintage year each one is ?

1] 2 Gani - Ala al din Mohammed Khilji
The date is off flan on your coin. On this type of coin the date is present in Nagari script in the circular margin in your left picture, starting at position 8.00 hrs clockwise

2] 2 Gani - Ghiyath al-Din Balban
This coins is not dated

Thanks again.
