It doesn't look fake to me. The reason that it looks 'different' is that 1834 was a year of change for bust half dollars - so it is different.
A new obverse master die was created with changes to the head, neck, and face. The letters and numbers were also different - large date and large letters, large date and small letters, or small date and small letters.
