I have inherited a set of china from my aunt with a blue and rust pattern. The bottom of the dinnerware says, "bone china, Coalport, made in england, est 1750, and Khotar at the bottom. There is also a mark of a crown at the top in between the words bone and china. I also have a Wedgwood service with what appears to be an urn or jug at the top followed by Wedgwood on one line then bone china, then made in england. There is what appears to be a handwritten "W 3927" in red and underneath that a red number 1 with a dot next to it. There is also the number 3 etched in to the bottom of the plate, not colored and difficult to see. The story my mother always told about this china is that she bought it a piece at a time in England where she was an Army nurse in WWII and mailed it home to her mother to hold for her. I have a service for 12.
Can anyone tell me about these two sets of china. I have been unable to find out much. I would appreciate it. I need to know if I have to insure these things or not...
