Royal Copenhagen Blue Flowers Braided 10” dinner plates. I have 4 but 3 are older and marked 8097, while 1 has the more recent numbering system 624. Both are the same.
The one numbered 624 is more recent than the others. It must have been purchased as a replacement. It is consequently in better condition and only has some light utensil wear.
The others are marked 8097 and have a bit more wear.
