We don't tend to discuss value much here, too subjective and way too many variables. Look at past results on auction sites and suchlike for an impression.
The shapes that Ivo showed in the other topic are generally associated with Art Deco, guessing maybe 1920s and into the 30s. Once in the depression years there was generally less disposable income for people to buy fancy goods, I expect these wares were a response to that situation. In glassmaking terms they are relatively simple, single colour blown to shape and then iridised, maybe less so for your compote but generally speaking fewer processes costing less to manufacture.
