The issue with the reverse legend ORÆ MARIT E.T / CLAS EX S C (Crawford 511/3b) is incomparably more rare than the usual type with CLAS ET ORÆ MARIT EX S C (Crawford 511/3a). This denarius was missing in all major collections of Republican denarii offered with the exception of that of Alba Roma (Pepe Fernandez Molina).
