cistophorus

The cistophorus (, kistophoros) was a coin of ancient Pergamum. It was introduced shortly before 190 B.C. at that city to provide the Attalid kingdom with a substitute for Seleucid coins and the tetradrachms of Philetairos. It also came to be used by a number of other cities that were under Attalid control. These cities included Alabanda and Kibyra. It continued to be minted and circulated by the Romans with different coin types and legends, but the same weight down to the time of Hadrian, long after the kingdom was bequeathed to Rome. It owes its name to a figure, on the obverse, of the sacred chest of Dionysus. Cistophoric standard It was tariffed at four drachmas, but weighed only as much as three Attic drachmas (the most important weight standard of the time), 12.75 grams. In addition, the evidence of hoards suggests that it did not travel outside the area which Pergamum controlled. It is therefore probable that it was overvalued in this area. In any case, the result was a closed monetary system similar to that in the Ptolemaic Kingdom. It is likely that this was a deliberate policy.
