caption_attribution_description: Heraclius. 610-641. AV Solidus (4.43 g). Struck 625/6-626/7. Carthage mint. dN ERA COMT P P ID (indictional year 14), crowned facing busts of Heraclius and Heraclius Constantinus VICTORIA AVCC IE (indictional year 15), cross potent on steps; CONOB. MIB III 83 (2) (mule of two different years); DOC -; SB 867. Following the reconquest from the Vandals in 533, Carthage became the civil and military capital of the prefecture of Africa. This issue has been dated with indiction years, rather than regnal years, this being part of a fifteen-year cycle used by the Byzantine fiscal authorities and marking the intervals at which tax schedules were revised.
context_page_description: In numismatics, a mule is a coin or medal minted with obverse and reverse designs not normally seen on the same piece. These can be intentional or produced by error. This type of error is highly sought after by collectors, and examples can fetch high prices.
  The earliest mules are found among ancient Greek and Roman coins. Opinion is divided between those who think that they are accidental, the result of an incorrect combination of a new die with one that had officially been withdrawn from use, or the work of coiners working with dies stolen from an official mint, perhaps at a time when one of them should have been destroyed.
  The name derives from the mule, the hybrid offspring of a horse and a donkey, due to such a coin having two sides intended for different coins, much as a mule has parents of two different species.
