SOLD 2.5" cobalt blue ribbed round in excellent condition.   The silvering on this item has a nice uniform antique patina all over and does not show much, if any light through.  The cap on this item is slightly mis-stamped and as a result has a bit of an overhanging rim on one side and is missing the same edge on the other side.  Note that the opening in our light box causes the dark shaped reflection in the photo.  

See pages 14.6 through 14.9 of the book for reference.
