1 Centavo Viana Do Castelo

Viana do Castelo issued its own fractional cédulas during the acute small-change shortage that gripped Portugal in the early 1920s — a crisis so severe that municipalities, parishes, and private firms across the country printed their own emergency scrip simply to make commercial transactions possible. These tiny municipal notes had no central authorization framework and circulated purely on local trust.

The MA#2302b designation places this within Manfred Müller's cédulas catalogue, the principal reference for Portuguese emergency issues of this period. At 43 × 39 mm, it is among the smallest pieces of circulating paper currency Portugal ever produced.
