50 Øre - Christian Magnus Falsen

This note belongs to the "Constitutional Heritage" commemorative series issued by Norges Bank to mark the 200th anniversary of the Norwegian Constitution — though the anniversary itself fell in 2014, making a 2020 issue date an outlier worth noting if confirmed. Christian Magnus Falsen was the primary drafter of the 1814 Eidsvoll constitution, often called the "father of the Norwegian Constitution," which makes his appearance on a circulating denomination a pointed choice over more conventional subjects.

The square format is the genuinely unusual element here — almost no modern circulating paper currency uses equal dimensions on all sides.
