This is probably the most common black glass jar.  Like most, if not all, jars this was made by Hemingray.  It has a glass lid with a zinc band as a closure.  The Royal has a bit of an odd ring since it has a couple of metal pieces sticking up on the outside.  These were intended to allow a screwdriver some leverage to help remove the lid.

This jar has a much rarer cousin in the black Royal of 1876.
