Vintage Texaco 25 Year Service Pin 14K Gold Robbins Clear Stone Screw Back Oil For Sale

Description:
Vintage mid-century Texaco 25-year service award lapel pin crafted by The Robbins Company of Attleboro, MA (the famed medalist known for producing NASA’s spaceflight medallions). Features the classic pre-1963 Texaco red star and green “T” emblem in white enamel, accented by a round clear faceted stone bezel-set above the logo. The octagonal face has a textured pebble background, raised “25 YEARS SERVICE” lettering, and winged detailing flanking the emblem.
Details:

• Maker & Hallmark: Reverse stamped “14K” beneath the Robbins Co. “Winged A” (Attleboro) trademark inside a diamond.
• Stone Details: Round clear faceted stone set with a traditional fine-jewelry open-back gallery hole (azurage) visible on the reverse. While 14K Robbins 25-year service pins from this era were traditionally issued with a small natural diamond melee chip, the stone has not been professionally tested and is therefore sold as an unverified clear stone.• Era: Mid-century (circa 1930s–1950s), featuring the pre-1963 Texaco emblem and vintage threaded post.
• Size: Approximately 13mm (just over 1/2 inch) across.
• Weight: Approximately 2.5g (weighed on a kitchen scale, pin only —backing removed)
• Fastener: Threaded post with removable screw-back nut included.
• Metal Content Note: Gold identification on the pin body is based on the stamped “14K” hallmark. The removable screw-back nut’s metal content has not been verified (vintage screw-backs are commonly brass or gold-filled for thread durability).
• Provenance: From my grandfather’s personal numismatic and memorabilia collection. Exact production year and original recipient are unknown (no personal engravings on the reverse).

Condition:
Good vintage condition with light surface scratches, small edge nicks, and warm age-related patina. The stone is secure in its bezel with crisp facets. The enamel retains strong color, with small surface marks and minor discoloration visible in the close-up photographs. Threads on the post and nut engage smoothly. Please examine the stone, enamel, reverse, ruler scale, and fastening details carefully.
Note: This listing is for the 25-year pin and its screw-back only. The 20-year pin shown in the comparison photographs is sold separately in another listing. The exact item pictured will be carefully packed in a protective box for shipping.
