Stater

Historical Context: This silver Stater was issued by the city-state of Koressia on the Cycladic island of Keos, dating to the Archaic period (520-510 BC). This era saw significant economic development and the rise of independent Greek poleis. Koressia, like its island neighbors, thrived on maritime trade. Issuing its own coinage, especially the Stater, highlights the city's economic autonomy and active participation in Aegean commerce, facilitating exchange for goods like wine and agricultural products.

Artistry: The design of this Stater exemplifies the Archaic stylistic school, an early phase of Greek numismatic art. The engraver remains anonymous, typical for this period. The obverse prominently features an amphora, a vessel central to ancient Greek life for storing and transporting wine or oil. This motif powerfully symbolizes Koressia's economic activities and maritime trade. The reverse typically presents an anepigraphic incuse square, a technical remnant of the early striking process, often displaying the punch's rough texture.

Technical/Grading: Weighing 9.83 grams and measuring 16.0 millimeters, this Stater adheres to the Aeginetan weight standard common in the Cyclades. Examination often reveals characteristics typical of early Archaic coinage: irregular flan shape, occasional off-center striking, and variable pressure leading to areas of flatness, especially on the amphora's high points like the handles and rim. The incuse square on the reverse may show variations in depth and clarity, reflecting the hand-striking methods of the era.
