RARE vintage Northern Pacific Railway 35-Year Service Award Pin!  Beautiful vintage railroad memorabilia featuring the iconic Northern Pacific logo, decorative gold-tone sunburst design, red inset stone, black enamel “35” designation and a pin-back fastening.  The reverse of the pin appears to be marked “10K”, indicating 10K gold. Please see close-up photos of the hallmark.  Northern Pacific Railway service pins were presented to employees in recognition of many years of dedicated service, making this a wonderful piece of railroad history as well as a unique vintage gold collectible.  Details: • Northern Pacific Railway • 35-Year Service Award • Appears to be 10K gold marked • Red ruby-like inset stone • Northern Pacific railroad emblem • Black, red and white enamel • Decorative sunburst design • Vintage original piece • Pin/brooch style fastening • Vintage patina and wear consistent with age • Please examine all photos carefully  PLEASE NOTE: The 10K hallmark is visible in the photographs but the metal and stone have not been independently tested.
