QUESTION: I'm slowly cleaning out my grandmother- in - laws home in Marietta. She has stuff in the house from generations prior, I was wondering if there is any books or web-site that can help me determine the trash from the treasure. She was a borderline hoarder in my opinion, I have found some exciting finds including a beautiful blue opal pitcher from the late 1800s. I am finding coins , jewelery, and many other items. It is going to be a long process. There are out buildings with old books, bottles, old tools. and so on. I have a friend who is helping me with some of the depression ware, and old fenton glass, I have e-bay and the internet as my other source of reference. Can you help me?
