Have a quart green in colar 3 L wax sealed ball standard jar with the roman numerals IV stamp in it I know it means #4 but does it mean something more then that? And what was the date on these jar?

If you are trying to determine the age of the jar and contents, I can only say, roman numerals are always used on clocks and other implements because it is classier to do so.

No, it doesn't mean more then what you a reading; someone wanted to use roman numerals, so they did.

Ancient romans did not use green quart jars, if that is what you mean, if not, please elucidate.
