Thông tin bổ sung

Historical Context: This Æ12 bronze coin was issued by the Thracian city of Bisanthe between 145 BC and 133 BC. This period falls within the late Hellenistic era, marked by increasing Roman hegemony. Bisanthe, a significant Propontis port, maintained civic autonomy, including the right to mint currency. The production of this small denomination bronze underscores the city's economic independence and its role in facilitating local commerce, reflecting a vibrant urban center adapting to geopolitical shifts.

Artistry: The specific engraver of this Æ12 is unrecorded, typical for ancient civic issues. Stylistically, the coin aligns with Hellenistic Greek numismatic traditions. While precise designs are not detailed, Bisanthe's coinage commonly featured iconography relevant to its identity. Typical obverse motifs might include a deity head (e.g., Dionysus or Demeter), while the reverse could display a civic emblem like grapes, a ship's prow, or a grain ear. The artistry aimed for clear, symbolic representations despite the coin's diminutive size.

Technical/Grading: This Æ12, weighing 1.31 grams and measuring 12.0 millimeters, is a modest bronze issue. For grading, critical high-points correspond to the highest relief elements of the design, such as hair or facial features on a portrait, or central details of a reverse device. Technical strike quality often varies; minor off-centering, uneven pressure, or weak strikes are common due to the small flan. A well-struck example, exhibiting good centering and full details on both sides, would be highly prized for its exceptional preservation.
