I was hoping to find more information on these glasses. I'm pretty certain there is very little value or collectability, but I always worry about replacing because there is deep sentimental value.
The first two pictures come from a set of 8. The 4 Single Old Fashioned glasses nest inside the 4 larger DOF glasses. The offset circle on the bottom makes me think these are mass produced pressed glass patterns but they are very nice quality in the hand.
The second pattern is from a set of two. They are heavy and the sharp points makes me think it is actually hand cut.
Any information or clues or directions for further investigation are welcome.
