Basically my best guestimate would be that these sets will start around $10 and if you're lucky, you might be able to go up to $30 or even more. I collect vintage glassware and while the stuff is gorgeous (and so awesome if you have the original box) - remember, these sets were owned by many, many people and you can easily find them at Goodwill, etc. So my best guess (just personal opinion) is the value would be between $10 and $30. Nice set!
