I'm a long time bottle collector and was asked by a friend to value this little jar. I've never seen one before so was hoping for input from this forum. Is it rare? What did it hold? I know Glenn & Co Perfumers succeeded L.W. Glenn around 1858 in Philadelphia, so was thinking this one may be Civil War period because of the shields. 4" tall,ground lip, glass is embossed vertically Glenn & Co with a shield embossed on front.
I gave the jar back to the owner so I can't take any more photos but the base is unmarked and not pontilled. The jar is embossed vertically Glenn & Co between the ridges of the jar and a shield is embosses horizontally on the front.
