From the Giovanni Maria Staffieri Collection; privately purchased from Numismatica Aretusa SA - Franco Chiesa, Lugano, in October 1982. From the pen of G.M.S.: Alexandrian Ptolemaic bronzes, particularly those struck during the 3rd and 2nd centuries BC in the highest denominations, were not only a means of exchange but also a testament to Egypt's political power and economic opulence. The obverse typically features the image of Zeus Ammon, the dynasty's favored deity, which is particularly striking on well-preserved specimens such as ours.
