Finland had issued its 5 pennia with a center hole since 1918, making the solid-flan wartime version a deliberate departure rather than an oversight. The change came because aluminum bronze was being conserved for the war effort, and punching out center holes meant wasted material the Helsinki mint could no longer afford to discard. The omission was utilitarian arithmetic, not a design decision.
KM#64.2 is the catalogued variety for the holeless type, distinct from the earlier KM#64.1.
