Tetradrachm - Demeas, Ermokles and Sosikra...

Historical Context: This Tetradrachm, issued by Athens in 93-92 BC, is part of the extensive "New Style" coinage (c. 165-86 BC). The named magistrates—Demeas, Ermokles, and Sosikrates—emphasize Athens' civic autonomy in minting, despite increasing Roman influence. This period showcases Athens' enduring economic and cultural prominence, producing coins vital for international trade. Its production immediately precedes Sulla's devastating siege of Athens (88-86 BC), which abruptly ended this prolific series.

Artistry: The design adheres to the Hellenistic aesthetic of Athenian New Style coinage. While engravers remain anonymous, the consistent quality points to skilled artisans. The obverse features an idealized head of Athena Parthenos, facing right, wearing an Attic helmet often adorned with a griffin. The reverse displays the iconic Athenian owl, standing on an amphora, flanked by the magistrates' names and the ethnic "ΑΘΕ." A distinctive control symbol, often a prow, appears in the field, aiding in precise dating and attribution.

Technical/Grading: This silver Tetradrachm, weighing 16.72 grams and measuring 30 mm, aligns with the Attic standard. Key high-points for wear on the obverse include Athena's helmet crest and nose tip. On the reverse, the owl's breast and the amphora's rim are crucial. These issues generally exhibit a strong strike, though minor flan imperfections or slight off-centering are not uncommon. The high relief of Athena's helmet can sometimes cause a corresponding flatness on the reverse directly behind it.
