American Numismatic Society - One of the really wonderful things about numismatic study is the way that coin types frequently look back to what came before. People are naturally conservative about the appearance of their money and find it easier to put faith in the value of coins that have the backing of tradition and public sentiment as well as of the issuing authority. Thus throughout the history of coinage, old typological friends, some of whom may have seemed long lost have had an uncanny way of coming back, sometimes even after very long intervals.

For centuries after the death of Alexander the Great, kings and cities copied his widely circulating tetradrachms with the types of Herakles's head and seated Zeus. So closely were the types associated with Alexander, that the image of Herakles soon became treated as his portrait in the guise of Herakles and continued in use long into the time of the Roman Empire. From time to time Roman emperors explicitly restored old and trusted denarius types while some of the towers depicted on Medieval deniers may ultimately take their inspiration from the ubiquitous "camp gate" types of the late Roman Empire. Somewhat more recently, the laureate head and seated female figure on the state coppers of Connecticut struck from 1786 to 1788 are suspiciously similar to the portraits of King George II and III and seated Britannia reverse of the well-recognized British halfpenny.
