Description:Vintage mid-century Texaco 20-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 cloisonné-style white enamel. The octagonal face has a textured pebble background, raised “20 YEARS SERVICE” lettering, and winged detailing flanking the emblem.

• 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 3g (measured on a kitchen scale — pin only, backer removed)
• Fastener: Threaded post with removable knurled 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).

Condition:
Good vintage condition with honest wear, including light surface scratches, small edge nicks, and warm age-related patina.

Please examine the front, reverse, ruler scale, and fastening details carefully.
