Vintage Chevrolet 'Service Supremacy' Award Coin/Token

This is a circular metallic award coin or commemorative token associated with the Chevrolet 'Service Supremacy' program, likely dating from the 1970s or 1980s. The coin is struck in a silver-toned metal, possibly pewter or a nickel-plated zinc alloy, featuring a brushed matte finish on the flat surfaces and blackened oxidation in the recessed areas to create a high-contrast 'antique' effect. The design features a central stylized 'SS' logo enclosed in a square border, which represents ‘Service Supremacy.’ Above this is the embossed text 'SERVICE SUPREMACY' in a sans-serif font, following the curvature of the upper rim. Below the central logo is the iconic Chevrolet 'Bowtie' emblem with the word 'CHEVROLET' embossed inside it. The reverse side is not visible, but these items were typically awarded to dealership service departments or technicians for achieving high performance and customer satisfaction standards. The craftsmanship is professional industrial die-striking with crisp edges on the raised lettering. Condition-wise, the token appears to be in excellent vintage state with minor surface abrasions consistent with light handling and no significant corrosion, deep scratches, or structural deformation. There is a slight patina visible in the crevices of the lettering, which enhances the legibility of the design.
