Colecção - Moedas e Notas - Diário de Notícias #18 - 18 mil reis

The Banco de Portugal's earliest note series of the 1850s came at a moment when the institution was still consolidating its monopoly on paper money issuance — a privilege formally granted only in 1846 after its merger with the Banco de Lisboa. The 18 mil réis denomination is an oddity by any standard; fractional-feeling values like this reflect a transitional monetary arithmetic rather than any clean decimal logic.

Printed domestically at a time when most Portuguese fiduciary issues relied on foreign presses, this note is among the earlier examples of in-country production for the Banco de Portugal series.
