Unable to find pattern name, so can not date them. They are in amazing condition, NO chips, NO cracks, NO repairs, NO crazing. This is what used to be called eggshell china, you can actually see the logo through the plate when held up to the light. There are TINY specks of gold missing on the rims and use marks from knives etc, but no dark marks. There is very moderate wear to the gold inner circles.
