Polupoltinnik - Aleksandr I

The polupoltinnik — a quarter-ruble denomination — had a troubled administrative history under Alexander I, who inherited a mint system still reorganizing after Paul I's erratic monetary reforms. The St. Petersburg and Kolpino facilities were both producing silver coinage in these early years, and the C#121 type spans a narrow window before production of this denomination was effectively discontinued in favor of larger silver issues.

The .868 fineness reflects the inherited Russian silver standard of 83⅓ zolotniks, unchanged since the mid-eighteenth century.
