Early imperial quadrantes do not have a portrait of the emperor. Some do not even name the emperor. I just got this one for the clarity of its legend and I added it to my site on quadrantes. http://augustuscoins.com/ed/quadrans/ A quadrans struck under Augustus in 9 BC. 17 mm. The coin does not mention Augustus, but does name three moneyers: LAMIVS SILIVS ANNIVS, around simpulum and lituus with the reverse naming their office: III • VIR • A•A•A • F • F (Triumvir Auro, Argento, Aere, Flando, Feriundo (Three men for gold, silver, and bronze, casting and striking). RIC I 421 page 74. "Scarce" 9 BC. I have an educational page on the quadrans denomination: http://augustuscoins.com/ed/quadrans/
