Gold Imari 6 tea cups and 6 small plates 2 big plates 1 chipped

I received these from a friend who was going to toss them out
They have a very faded blue marking on each cup but all plates the mark is not present or faded
She's had them 10+ years and her grandmother had them before her
They are hand painted for sure and very pretty
2 bigger plates and 6 tea cups and 6 small tea size plates
One big plate is chipped which you can see in a pic I posted
I want to know if these are reproductions or originals
And perhaps a value?
They are beautiful and I wall hang some on my dining wall
