There has been so much glassware manufactured in the last 100 years, its really hard to keep up! Even if you can’t identify the pattern or the manufacturer, you could always find a buyer that just likes it and wants to use it or display it. My first thought was depression glass era too, but I’m not 100% certain. However, I believe your etched glassware is worth around $2-3 dollar each. So, in my opinion the whole set is worth around $75-125 dollars. Here is what I based that on:
