The stamp commemorates the 13th Congress of the Postal Union of the Americas and Spain (UPAEP), an intergovernmental organization fostering cooperation among postal services in Latin America, Spain, and Portugal. The UPAEP, established in 1911, plays a significant role in standardizing postal services and fostering philatelic exchange within its member countries. This issue specifically highlights Nicaragua's hosting of the event in 1981, marking a moment of regional diplomatic and logistical coordination in the postal sector.

How does authenticity detection work?

PHILATELIST'S VERDICT

Philatelist

Stamp Specialist

The stamp is clearly identifiable by its country, year, denomination, and commemorative event, all visible in the images. The condition appears sound, suggesting a straightforward identification.

KEY EVIDENCE

  • 1The inscription 'NICARAGUA Aereo 1981' clearly identifies the country, type, and year of issue.
  • 2The denomination '₡ 3.00' is clearly printed.
  • 3The text 'Congreso de la Unión Postal de las Américas y España MANAGUA: NICARAGUA 1981' confirms its commemorative purpose.
  • 4The visible perforations and lack of cancellation indicate an unused stamp.
  • 5The design of a modern building and statue is typical for an official commemorative issue.

UNCERTAINTIES

  • Assessing the gum condition (hinged vs. never hinged) requires physical inspection.
  • Exact centering, while appearing good, would need to be measured against a gauge for precise grading.

WHAT WOULD IMPROVE CERTAINTY

  • Examine the reverse side for gum condition (Original Gum, Never Hinged, lightly hinged, no gum, regummed).
  • Measure the perforation gauge to confirm standard issue specifications.
  • Check for watermarks using a watermark tray, as this can be a key identifier for some Nicaraguan issues.
  • Consult a relevant stamp catalog (e.g., Scott Standard Postage Stamp Catalogue) for the definitive catalog number, specific color varieties, and known errors.
  • Use a magnifiying glass to inspect for printing flaws.

CONDITION & GRADE

Condition

The stamp appears to be in very good condition with no visible creases, tears, or significant discoloration. Centering seems acceptable, though a more precise measurement would be needed. The lack of a cancellation mark suggests it is unused.
