- Photograph the logo, front embossing, base, lid, closure, color, mouth, and size.
- Separate screw-top jars, wire-bail jars, zinc lids, glass inserts, and unusual colors.
- Check for chips, cracks, haze, staining, replaced lids, and mismatched closures.
Key value drivers
Age helps only when it connects to rarity and condition. Scarce logos, unusual closures, strong color, original lids, clean glass, and complete examples matter more than age alone.
