Hi,
this coin should be 2014! It's the only date written on the coin and it's impossible to guess, that it might have been released in 2015!

This is a general problem with Indian coin years in the Numista catalog, which is a crazy way of reasoning. When on the coin you only find, like here 1914-2014, then it should be 2014 you search for and NOT any other year (like 2015 or whatever)!
Any other opinions on this?
Here another example
