Mobiloil Porcelain Sign Value Guide

The Mobiloil porcelain sign is a cornerstone of American petroliana, featuring the legendary red Pegasus logo adopted in 1932. These signs represent the golden age of motoring and are prized for their vibrant enamel finish and association with the expansion of U.S. gas stations.

What affects the value of Mobiloil Porcelain Sign?

• Overall surface gloss and the absence of 'shelving' or porcelain chips, especially within the Pegasus graphic.
• The presence of original brass mounting eyelets and minimal rusting around the bolt holes.
• Rarity of the specific size, with larger dealership versions often commanding higher prices than standard pump plates.
• Authenticity of the era, specifically pieces dated between 1930 and 1950 with original manufacturer stamps.

How to Identify Mobiloil Porcelain Sign?

• Look for the 'IR' or 'Property of Socony-Vacuum' markings often found along the bottom edge.
• Inspect the red Pegasus logo for sharp, multi-layered porcelain enamel that creates a slight physical depth.
• Check for authentic mounting grommets and heavy-gauge steel that resists bending more than modern reproductions.
• Verify the specific shade of 'Mobil Red' and 'Mobil Blue' which should remain vibrant due to the glass-fused finish.
