Common. This is a specimen note from a standard 1979 issue by the Banco Central de Nicaragua. The eBay market data provided shows specimen/UNC examples trading in a wide range ($1.99–$73.14 USD), with most specimens selling in the $2–$5 range, indicating these are readily available on the secondary market. Specimen notes, while technically not released for circulation, were produced in significant quantities for distribution to banks, governments, and collectors. The lack of scarcity in market pricing and the straightforward historical context (not a rare error, short-lived currency, or recalled issue) confirms this specimen as common in the collector market.

This banknote was issued on August 16, 1979, shortly after the Nicaraguan Revolution and the formation of the Junta de Gobierno de Reconstrucción Nacional (National Reconstruction Government Board), as noted in the decree inscription 'Año de la Liberación' (Year of Liberation). The note commemorates General Augusto Cesar Sandino, the legendary Nicaraguan nationalist hero who led resistance against foreign intervention in the 1920s-1930s. The imagery—combining Sandino's portrait with his humble birthplace—reflects the revolutionary government's emphasis on national heroes and popular legitimacy during this transformative period in Nicaraguan history.

The obverse features a three-quarter portrait of General Augusto Cesar Sandino positioned on the right side, depicted wearing his characteristic wide-brimmed cowboy hat. The central design element is an ornate oval frame containing the denomination '1000' in bold numerals. The overall color scheme is predominantly beige and gray with navy blue accents and decorative guilloche patterns throughout, creating a classical banknote aesthetic. The reverse depicts 'Casa Natal de Sandino' (Sandino's Birthplace), a traditionally constructed dwelling with a thatched/shingled roof and wooden architecture representative of rural Nicaraguan construction, positioned on the left side. The reverse employs a more colorful palette with yellow, light blue, and green gradient backgrounds complementing the traditional building engraving. Both sides feature intricate geometric and ornamental design elements within decorative frames, and both bear the red diagonal 'MUESTRA COMERCIAL' specimen overprint.

This note was produced using traditional engraved intaglio printing by Thomas de la Rue, London, as confirmed by catalog data. The visual characteristics—including the fine guilloche patterns, detailed portrait engraving of Sandino, intricate geometric designs, and precise line work visible in the ornate frames—are consistent with high-quality intaglio engraving. The multi-color printing on the reverse with gradient effects and the crisp definition of security features indicate advanced security printing techniques employed by this renowned British security printer. The specimen overprint was applied separately as part of the specimen marking process.

This is identified as a specimen note (designated by the '-s' suffix in Pick P-139s) characterized by the red diagonal 'MUESTRA COMERCIAL' overprint. The visual analysis indicates this is 'SERIE E' (Series E), which may represent a specific production run or signature variety. No significant printing errors or unusual overprint varieties are apparent from the visual inspection. Standard signature varieties would be expected for this issue, though the specific signatures are not clearly legible in the provided images. The specimen status distinguishes it from circulating examples of P-139.
