Mystery antique plates/platters
I was given these beautiful plates by my MIL, and she got them from an estate on Long Island. They appear to be very very old, and hand painted. They are quite heavy. The two platters have been broken and professionally repaired with some type of staple, which makes me think they must have been quite special. They have a cream background, that has a lot of crazing, and gorgeous cobalt blue, rose, green, and gold painting. I have two plates, two platters,and two plates with deeper centers, which I suppose could actually be bowls. The only markings on the back are very tiny gold numbers, that look handpainted on. They read "4330" and I just couldn't get a good picture of the numbers because they are so tiny.
I know nothing about their age, what they're made of, or if they are worth anything. I think they are beautiful regardless. Any info appreciated!!
