Hi everyone! I'm new here. :] I have a vintage punch bowl set that was given to me by my mother, and I am wondering how much it's worth. I have no information on it other than it belonged to my grandmother/possibly great grandmother(?). I do not see a brand or logo on it, and it does appear to have a seam on either side of the bowl so I assume it is not real crystal? It has 10 cups. Any help and info will be greatly appreciated! :]
