Denga - Mikhail Borisovich

Historical Context: The Denga of Mikhail Borisovich (1461-1485) from the Grand Principality of Tver marks the twilight of its independent sovereignty. Mikhail Borisovich, Tver's last independent Grand Prince, navigated a precarious geopolitical struggle between Muscovy under Ivan III and Lithuania. This coinage asserts Tver's distinct authority and economic autonomy during intense pressure, culminating in its annexation by Moscow in 1485. It is a crucial artifact reflecting a pivotal moment in the consolidation of the Russian state.

Artistry: While a specific engraver for HP II#7225A is unattributed, denga of this era were products of local mints, displaying a rustic yet distinctive stylistic school. Designs commonly featured a horseman, often interpreted as the prince or a saint, or intricate Cyrillic legends bearing the ruler's name and title. The small flan (0.55 gg) necessitated compact designs, rendered with primitive vigor rather than refined artistry. Hand-engraved dies led to considerable die variety and charming idiosyncrasies.

Technical/Grading: Given the diminutive size and weight (0.55 gg), the technical quality of these silver denga varies significantly. High-points for wear or strike typically include the horseman's head, weapon, or the uppermost portions of Cyrillic letters. A well-struck example exhibits full legends and a clear central device, though off-center strikes and weak areas from uneven hammer blows are common. The irregular flan shape, typical of medieval Russian coinage, impacts overall presentation. A sharp strike on a well-centered flan is exceptionally rare and highly prized.
