Can you tell me what pieces you have?
Can you send me picture of these?
No, we can wait until you can send a picture unless you know what pattern they are?
yes they are valuable, there were a few patterns that Mother's Oats used,. depending on the pattern is who determines the value. They made a Sandwich Glass Pattern , a Rose of Sharon Pattern, and also a Star of David Pattern. All of them have value each pattern has it 's own value.
If you can describe the pattern then I am sure I will know which one you have .
Ok, that would be great, that will help a lot with the value.
