This is an extremely rare pint Ravenna was sealer.  Ravenna jars have a peculiar appeal to collectors for some reason.  They are certainly very rare and early jars and the pontil is desirable.  Anyway, there are a few people out there who would like to get one of these.

The top of all these ravenna jars has a really rough inner channel.  You can just barely see it over the top of the smoother outer channel in this picture.

A great jar whose greatness I really didn't recognize when I first bought it but have come to appreciate over the years.
