Original blue glass jars were only made until 1937, but the company has released reproductions more recently

Errors in the lettering make the jar especially valuable. For example, look for jars where PERFECT is misspelled as “perffct,” “peprect,” and “perefct.”

Original lids were mostly made from zinc and included a milk glass lining. Even more rare are the solid glass “Lightning” lids.
Jars with original lids are generally worth 50% more than a similar jar without a lid!
