Bow and bowcase counterstamps on Alexander-type and Side tetradrachms, with different legends, have been attributed to cities within the the Kingdom of Pergamon (Pergamon, Ephesos, Tralles, Sardes, Synnada, Apameia, Laodiceia, Stratonikeia, Adramytion, and Sale). Price has linked these counterstamps to the introduction of the cistophoric coinage in the 180s BC. The application of these counterstamps permitted the circulation of Attic weight coins in the years following the reform. See R. Bauslaugh, "Cistophoric Countermarks and the Monetary System of Eumenes II" in NC 1990.
