Need help Jar not in REDBOOK

[creeper71]

I seen a jar at a flea market it was a MASON'S arched under that was a Monogram I think it was SGCO then under that Patent Nov 30th with dash under th then 1858 it was a Aqua Quart with a ground lip.. anyone know value I am thinking of buying it but I know nothing about this jar an the price I thought was a lil steep if it is a common.. sorry no pic since it was in a flea market. I checked RB#9 couldn't find the jar in there
