Does this stuff work with Lego MINDSTORMS EV3? Because I have an EV3 edition and it's a little different than the NXT version.

  It does not count them, it detects the coin by measuring the angle that the coin leaves when inserted between the two bars. Different coin => different size => different gap between the bars.
  
  Note that this is of course a very crude way to detect the coins. It will not work with unknown coins and it will have a hard time to distinguish between two coins with very similar radius.
