History & Identification

Your jar is an authentic early 20th-century Ball Mason jar, likely produced between 1920-1923. Ball Brothers started making glass jars in 1880, and their Ball script logo evolved over time, which helps date jars.

• The "Ball Blue" color was made from sand sourced from Indiana, which had a natural bluish tint.
• The molded bubbles and dimples indicate early manufacturing techniques before fully refined glass-making methods.
• The number on the bottom (6 or 9) is a mold number, not a year or specific date code.

Value & Collectibility

Factors affecting value:
✔ Age & Rarity: 1920s Ball Mason jars are collectible but not extremely rare unless they have unique markings.
✔ Color: Ball Blue jars are desirable but were widely produced.
✔ Condition: Excellent condition increases value, especially with no chips or cracks.
✔ Lid Presence: If the original zinc or glass lid is intact, value increases.

Estimated Value:

• Common Blue Ball Mason Jar (1920s): $10 - $30
• If rare mold variation or error: $50 - $100+
• With original glass lid and good condition: $40 - $60

Higher-value variants include jars with unusual embossing (e.g., "Perfect Mason" or rare logo variations).

Selling & Professional Appraisal

If you plan to sell:

• eBay, Etsy, or Facebook Marketplace for collectors.
• Antique stores or flea markets may offer quick sales.
• Auctions (like Ball jar collector groups) could fetch higher prices.

If you believe your jar has unique markings, an error, or an unusual mold, a professional appraisal may be useful.
