This unique aureus features a heretofore unknown issue, struck from dies previously known for two separate aurei. The obverse die is from the rare issue that celebrates the association of Antoninus Pius with Marcus Aurelius as Caesar (Calicó 1734) dated to AD 140. The reverse is known only from a unique aureus in a private collection dated tentatively to AD 140-143. With the addition of this new unique aureus, the Calicó 1467a coin (unlisted in Cohen, BMCRE, and RIC) can more accurately be dated to AD 140, as it almost undoubtedly was struck alongside the Pius and Aurelius as Caesar issues, since they share die links. Thus, this unique aureus, alongside the Calicó 1467a coin, should be placed with the Antoninus Pius and Marcus Aurelius as Caesar aurei section of Calicó 1719-1735. Together, they constitute two supreme rarities with artistically composed anepigraphic reverses. Furthermore, these two coins are now better understood as deriving from the aurei emission of AD 140 and can be appropriately placed in that context.
