Antique Ball Perfect Mason quart jar in aqua blue — Mold No. 9 — with original milk glass zinc lid, dated to the 1920s. Professionally packed for fragile shipment. Ships next business day. Full refund if damaged in transit.
The mold number stamped on the base of a Ball Perfect Mason is one of the primary collecting markers in this category, and Mold No. 9 is among the more sought-after numbers. Ball produced its jars using numbered molds across multiple glasshouses, and certain mold numbers appear with noticeably lower frequency in the surviving record — No. 9 is one of them. The combination of a documented scarce mold number, the aqua glass color, and an original lid in place makes this a more complete and desirable example than a lidless jar of the same variant.
The milk glass zinc lid is the original period closure — the white opaque glass insert sits inside the zinc band and was designed to prevent the zinc from contacting preserved food. This lid shows appropriate age patina consistent with the jar. Glass body is free of chips or cracks. Embossing is sharp.
