If it is a graphic symbol of "golden Dawn" then it would be the Noritake "Komari" line. This would be valuable since it was a porcelain glazed setting that was first made and marketed as Japan was just opening to the West. The symbol is a golden dawn sunrise symbol with the rays all squiggly.
Rookwood did a sunrise symbol on their original 1921 patent. However, They didnt make any plates (except for a tea set or two) . They were mostly all stomeware.
WENTZ "Westward Ho" and STAR also made some pottery with the sunrise symbol(no plates that Im aware of)
