Note: The following note was attached to a coin of this type for sale by Sayles and Lavender in October 2007: "It was long assumed that these anepigraphic coins featuring the head and symbols of Asclepius were from Pergamum in Mysia, seat of the great cult center to the god of healing. However, Butcher's recent scholarship shows that they are certainly either Antiochene or of north Syrian origin. During the reign of Domitian there was constructed on the slopes of Mt. Silpius at Antioch a temple to Asclepius. Since the coins carry no ethnic or mark of denomination, it seems plausible that these were issued as temple tokens rather than as coin of the realm."

If this is correct, these pieces would date from the first century CE.
