Mason Jar Patent Nov 30th 1858 with an iron cross on the the back?

[jtereshamr]

It is blue, with screw on metal type lid, and there are air bubbles in the the glass, and on the bottom it says
PATNOV 2C C7 with a big 46 in the middle. And on one side it has an iron cross and the other side it says Mason Patent Nov 30th 1858.
Does this jar have any special significance? From my previous research I was told it could be worth upwards of $10,000. Does anyone know more about these types of jars? It is an odd shape too, kinda tapers up to a small mouth with the metal lid.
Thanks!

Without a picture of the jar and its marks, it is very difficult to determine if your particular jar is worth anything.  Many people collect Mason Jars that vary in value from a few to hundreds of dollars.  I know that certain colors are more rare than others and obviously, condition has a lot to do with value also.  I don't collect the jars, but the history behind them has always interested me.  November 30, 1858 is the year that Mason obtained a patent for his jars and about 20 years later, that patent was sold to someone else.  Here are a couple of places you might investigate:  www.balljarcollectorscommunitycenter.yuku.com (If I remember correctly, there is a section about "non-Ball jars" and you also might post a picture of your jar and ask for help.  Some people on that sight are pretty knowledgeable.) and in Kyle Husfloen's book Antique Trader Antiques & Collectibles 2008 Price Guide, there are a few pages devoted to Mason Jars.  The book isn't too expensive to purchase and although you're looking for a specific topic, the book is really interesting.  Perhaps a library would have a copy also.  I can't locate my copy, so I can't give you details.  Good Luck!

Look closely at the "iron cross"

Hero Fruit Jar Company of Philadelphia, represented by the Hero Cross. The Hero Cross looks similar to the Iron Cross, but careful examination will revel that the Hero Cross is unique, and if the jar is well embossed, you will see in the arms of the cross a H, F, J, and Co, one in each of the four arms.

taken from http://www.longislandantiquebottleassociation.org/news/newssep06.htm scroll to the article near the bottom of the page on canning jars.

This page http://www.hoosierjar.com/soldjars.html shows a jar like the one you have described but they don't have the price listed since it has been sold.... why do people do that 

The price you were quoted seems pretty steep as there are some that have sold at auction for $5.00 - $30.00.
