Actually, I should have been specific but you did what I needed to see. The lid is of no more value than any other, the really good ones have embossed letters on the milk glass insert AND incuse (indented / stamped) letters and / or figure on the zinc part. Those with only embossed lettering on the glass part are common. No problem though, it's still a decent jar & lid.
Welcome to the site...looks like your jar is #1512 in Red Book , a price guide to North American, British and Australian jars. Your jar, clear or aqua HG is worth $10-12, just as epakage mentioned. It was made somewhere in the U.S.A. Another way to find out more jars is to post it on the JAR forum on this website. There are many more knowledgeable pros lurking in the background that may offer their impressions.
