This is a hard-to-find Richard Ginori white plate with a gold crest with a crown.  I am not sure if this hotel or restaurant ware or the age but I would think this would be from the 1960's to 1970's.  At the same time I found this plate I found some other hotel plates from the same era.  This measures 6.5" in diameter and is in great condition except for a small stain near the gold crest.  It is marked as shown in the pictures.  Thanks for looking and be sure to check out my shop, not2shabbyshop, for more fabulous finds!
