附加信息

Historical Context: The 1 Cash Thuận Thiên Đại Bảo coin represents a pivotal moment in Vietnamese history, issued during the reign of Lý Thái Tổ (Lý Công Uẩn), founder of the Lý Dynasty (1010-1225). This coinage marks the establishment of a stable, independent Vietnamese state, Đại Việt, following centuries of Chinese domination. The era saw the capital move to Thăng Long (Hanoi) and consolidation of imperial power, with these coins serving as a tangible symbol of national sovereignty and economic stability.

Artistry: While specific engravers remain anonymous, these coins reflect the prevalent East Asian cash coinage tradition, crafted by imperial mint artisans. The design features the four characters "Thuận Thiên Đại Bảo" (Thuận Thiên Great Treasure) on the obverse, read top-bottom, right-left, rendered in a strong, clear calligraphic style. The reverse is typically plain or features a simple dot or crescent, characteristic of early Vietnamese issues. The aesthetic emphasizes legibility and the symbolic weight of the dynastic inscription.

Technical/Grading: As a cast copper coin, strike quality varies significantly. Key high-points for evaluation include the sharpness and integrity of the calligraphic strokes, particularly their serifs and intersections, and the definition of the inner and outer rims. Common technical considerations involve centering, planchet uniformity, and the presence of casting flaws like sand holes or uneven edges. A well-preserved example exhibits a rich, stable patina and minimal wear to the raised characters, reflecting its circulation during the early Lý period.
