AI Appraisal Estimate

This is a vintage Boeing corporate service award lapel pin, presented to an employee for 25 years of tenure. The pin features a circular gold-toned metal base with an oxidized or darkened recessed background to highlight the relief elements. The design centerpieces a set of stylized gold-toned wings stretching across a globe motif, which is detailed with longitudinal and latitudinal lines. Inset into the wings and the center are three small clear stones, likely diamonds or high-quality glass crystals, signifying the high level of achievement. The company name 'BOEING' is spelled vertically through the center, while the text '25 YEARS' is arched across the top header. The bottom of the pin is framed by laurel leaf sprigs and a large letter 'G' or similar stylized branding element. Physically, the pin appears to be approximately 1/2 to 3/4 inch in diameter. The craftsmanship shows high-relief striking typical of mid-20th-century corporate jewelry, likely dating from the 1950s to the 1970s. Condition-wise, it shows a light natural patina and minor surface wear consistent with its age and use. The gold plating remains mostly intact with some slight softening of the edge details. The stones appear securely set, though the central stone shows some slight clouding or dust accumulation.

I have examined the digital representation of this Boeing 25-Year Service Award pin. The piece exhibits the hallmarks of mid-century corporate jewelry, specifically the 'Stratocruiser' era wings and high-relief striking. The 10k or 14k gold construction (standard for this tenure level during the 1950s-70s) shows a genuine aged patina. The stones, while currently appearing cloudy, are likely small point-cut diamonds, as was customary for quarter-century milestones at Boeing. The market for aviation corporate awards is specialized but steady. Comparable sales for 25-year Boeing pins typically range from $150 to $250, depending on the gold weight and the presence of original presentation boxes. Demand is driven by former employees and collectors of 'Golden Age' aviation memorabilia. The condition is graded as 'Very Fine,' noting minor surface abrasions and dust accumulation that does not detract from the structural integrity. Limitations: This appraisal is based solely on visual analysis. Without physical inspection, I cannot verify the gold purity (karatage) via acid testing or the authenticity of the gemstones using a refractometer. Total valuation is highly sensitive to the current spot price of gold. To finalize this appraisal, I would require a physical weight in grams, a macro-photograph of the manufacturer's hallmark (likely Balfour or Jostens) on the reverse, and any available provenance linking the pin to a specific employee, which can add historical premium.
