I'm hoping someone can help or point me in the right direction. When my Mom died I "inherited" different types of glassware that used to come, I believe, in detergent boxes back in the 50's. There are various sizes, shapes and colors. There are 4 to some sets, 6 in others, and so on. Many of the rims have chips, some do not. Here's are my questions, is it worth it to "sand" these glasses so they are useable? Do they or will they have any value? I ask because they do take up a lot of room and it doesn't appear that my daughters have any interest in them. Any and all suggestions and help are welcome. I thank you in advance.
