This is a 1944 Banco Nacional Ultramarino 50 avos banknote from Macau, graded AU, representing an important piece of Portuguese colonial currency history. The note displays the characteristic purple and cream color scheme of mid-20th century Macau currency, with intricate geometric borders, bilingual Portuguese-Chinese inscriptions, and a handwritten manager's signature in the lower right. Despite visible signs of age and light circulation, the note maintains excellent definition in its fine line engraving and decorative elements, making it an attractive example of this denomination.
Common. The 1944 50 avos Pick-21 is a standard denomination from Banco Nacional Ultramarino's regular currency series for Macau. No documented print run restrictions, recall issues, or short-term issuance exist for this note. While circulated examples from this era show wear, AU-graded specimens remain readily available in the collector market at modest prices, typically under $30-40 USD, consistent with common wartime colonial currency of this denomination.
Issued during World War II by the Banco Nacional Ultramarino—Portugal's overseas banking institution—this 50 avos note reflects Macau's status as a Portuguese colonial territory with significant Chinese commercial influence. The bilingual design incorporating Chinese characters (伍拾) alongside Portuguese inscriptions demonstrates the multicultural economic environment of Macau during this period. The heraldic coat of arms and formal banking designations ('GERENTE') underscore the Portuguese colonial administrative structure that governed the territory until the late 20th century.
The 50 avos note features a symmetrical design with a central heraldic coat of arms—representing Portuguese sovereignty and the Banco Nacional Ultramarino's authority—positioned prominently in the upper center. The coat of arms is surrounded by ornate scrollwork and classical decorative motifs. Circular denomination emblems (featuring '50' and Chinese characters '伍拾') occupy all four corners, reinforcing the value in both Western and Chinese numeral systems. The series designation 'F' appears on both left and right sides. The handwritten managerial signature in the lower right corner authenticates the note. The overall design employs fine line engraving with intricate crosshatching and geometric border patterns typical of security printing from this era.
Front side inscriptions: 'BANCO NACIONAL ULTRAMARINO' (National Overseas Bank); 'CINCOENTA AVOS' (Fifty avos); 'MACAU' (Macau); Serial number 'No.8233578'; Chinese denomination '伍拾' (Fifty); 'GERENTE' (Manager); 'AVOS' (avos); Denomination numeral '50'; Series letter 'F'. The bilingual presentation combines Portuguese colonial authority with Chinese cultural recognition, typical of Macau's unique administrative status.
This note was produced using intaglio (relief) engraving, evidenced by the fine line work, precise geometric patterns, and detailed crosshatching visible throughout the design. The multi-color printing (purple/mauve and green accents on cream stock) indicates sequential plate printing, a standard technique for Banco Nacional Ultramarino currency of this period. The crisp definition of the heraldic imagery and the precise registration of bilingual text suggest professional security printing standards maintained by the Portuguese central bank's printing facilities.
This specimen belongs to series 'F' as noted in the collector data and confirmed by the visible 'F' designations on the note itself. The serial number is 8233578. Series letters were used by Banco Nacional Ultramarino to track different printing runs; the 'F' series is a standard documented variety. The handwritten manager's signature is typical of this issue and not a distinguishing variety factor. No unusual overprints or date variations are observed.
