I ask a very basic question: Is the direction of the Emperor's portrait/bust really important to the rarity/scarcity of an ancient coin? I noticed that most of the coins of Alexander The Great, Julius Caesar, Augustus etc. have right facing portraits, unlike GB coins where the ruler's portrait generally alternated with every successor. Acquired this Aureus recently and although I've seen several examples with a right facing portrait, I've not found any example with a left facing one. Am I safe in assuming it is a rare coin and I should be pleased with my acquisition?!! A keeper then even if its no better than a 'Fine' grade? The coin itself shows one of the Emperor's ill-fated grandsons and heir (Gaius) on horseback: Augustus AV Aureus. Lugdunum, 8 BC. AVGVSTVS DIVI F, laureate head to left / C•CAES AVGVS•F, Gaius Caesar on horseback, galloping to right, aquila between two legionary standards in background. RIC -; C. 41; Calicó -. 7.80g, 19mm, 6h.
