Answer 1

it's worth whatever the highest bidder is willing to pay!!!!!!

While the previous answer is true in the most general terms, it doesn't answer the question in any valuable way.

Mason Patent "November 30th 1858" jars were patented in, of course, November 30, 1858. These jars were made well into the 1900's, most recently, to my knowledge, in the 1970's or 1980's as large pickle jars. Most jars are found in the quart size, with pint and half gallon sizes found less frequently.

There are many colors of these jars, ranging from aqua to olive green and yellow. Aqua is the most common color, other colors increase the value of these bottles. True Mason's patent jars typically have a zinc screw on cap with a milk glass liner. Older jars may have bubbles or "hammering" in the glass, crude lettering and a rough cut top edge.

Values on original Mason Patent jars range from $8-$12 for an average aqua jar with no outstanding features. Values go up into the high hundreds for a rare version.

If the lid on this jar, as I suspect, is more like that on a modern jar, it is probably a reproduction used to market pickles in the 1970's or 1980's - this jar, while not common is not very valuable. It would sell for about $20 or so, though you can find some trying to sell for as much as $100. This is where the first poster's observation comes in. If it is actually an older one the value could get much higher. Without photos it is impossible to make a guess.
