50 Francs / Franken / Franchi

The Banque Cantonale Neuchâteloise was one of several cantonal banks operating under Switzerland's pre-federal banking patchwork, issuing their own notes before the Swiss National Bank absorbed that function after 1907. This note falls squarely in the transitional window — the SNB opened in 1907, and cantonal note-issuing privileges were wound down progressively, which means later dates within this series were among the final emissions before Neuchâtel's independent circulation rights lapsed.

The trilingual denomination line — Francs, Franken, Franchi — reflects the constitutional requirement to acknowledge all three of Switzerland's major language communities, not any particular circulation geography for this note.
