DJR Expert Guide Series, Vol. 597 — How to Identify Valuable Vintage Signs & Advertising Items
Vintage signs—porcelain, tin, cardboard, neon, dealership signs, gas pump globes, and advertising displays—are among the hottest categories in antiques today. Early gas & oil brands, soda companies, automotive manufacturers, farm equipment brands, and general-store signage all command strong collector demand. But because value is high, the market is flooded with reproductions, fantasy pieces, and artificially aged signs.
DJR Expert Guide Series, Vol. 597 provides a complete, beginner-friendly, non-destructive workflow for identifying valuable vintage signs and advertising collectibles. This guide teaches you how to evaluate materials, mounting holes, age clues, graphics, patina, maker marks, and brand history using the same observational methods trusted by professional appraisers.
Inside this guide, you’ll learn how experts:
Identify major sign types: porcelain, tin, cardboard displays, neon, plastic, fiberglass
Evaluate materials and construction traits to determine authenticity
Recognize true age indicators such as natural rust, layered enamel chips, and UV fading
Distinguish real porcelain signs from modern reproductions using thickness, gloss, steel base, and enamel layers

Spot pixelation, incorrect fonts, misaligned colors, and other reproduction giveaways
