You've already pointed yourself in the right direction by identifying the broken fourth right star and unbroken r. The next step will narrow the choices roughly in half by determining if LIBERTY is doubled or not. In the attached link attribution guide #4 is doubled LIBERTY and guide #3 is not. I can't make out the S/S mint mark in your image but there are several listed.
