What Is Mobiloil Porcelain Sign Worth?

The typical price range for Mobiloil Porcelain Sign is $1,500 - $1,800 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• 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.
