| Additional information |
Finland's penni coinage was authorized following the 1860 monetary reform that made the Finnish markka an independent currency unit, severing the Grand Duchy's monetary dependence on the Russian ruble system. Alexander II personally approved the reform — a calculated political concession to Finnish autonomy that stopped well short of actual independence. The Helsinki Mint, reestablished specifically for this purpose, struck its first penni pieces in 1864.
The 1866 issue is known to exhibit inconsistent copper alloy quality traceable to early supply chain problems at the mint.
