20 Pennia Reverse Trial

Finland's coinage in 1866 was still being worked out under Russian imperial oversight — the markka system had only been formally established in 1860, and the Helsinki Mint was navigating both new denominations and new design approvals simultaneously. Trial pieces from this period, particularly reverse trials, reflect the iterative approval process required before dies could be sanctioned for full production. Holmasto 280 is genuinely scarce in any form.
