A vintage Canadian-made glass canning jar with a wire-bail seal. ÉPOQUE Circa 1930s ORIGINE Canada VALEUR ESTIMÉE I estimate this vintage Safety Seal jar to be valued between $15- $25 CAD. HISTORIQUE Safety Seal jars were a popular choice for home canning in North America during the early to mid-20th century. These jars utilized a mechanical wire-bail system to create an airtight seal, reducing the reliance on separate screw-top lids. They were widely used for preserving fruits, vegetables, and jams in rural households. Canadian-made versions of these jars are common collectibles today, valued for their utilitarian aesthetic and historical connection to domestic life. The 'Made in Canada' mark indicates a regional production that mirrored the larger trends in the canning industry. Collectors often seek these for rustic kitchen decor or as examples of early industrial glass design
