@minni, your new pics are pretty good, but you still aren't giving us a clear indication of where you are seeing the die clash with the coin in hand and it isn't super evident from the pics. For example, I see a distinct line coming from the dome and heading toward the M of UNUM (see red arrow below). From these pics, that looks like a difference in surface toning though rather than ghosting or die clashing.
