I finally am going through some boxes of my dad's belongings and came across a collection of what appears to be a combination of Flow Blue and Chinese Blue and White. I vaguely recall them in my grandmother's house growing up in Vermont. I expect at least some if not all of them were from my great grandmother in Billerica, MA.

I am trying to figure out what I actually have here. Most pieces have 3 pictures - a close up of any markings, the bottom of the item, and the front. There are a couple of pieces with chips, but most are in decent condition.

Besides using this site to identify my pieces, where can I learn about what I have and their value (do I need to insure, etc)?
