I am by no means an expert on antique and vintage plates. This is a plate my mother had in her collection. My parents were antique dealers many years ago which leads me to believe that this is an authentic antique or vintage item. From my research I have determined that this 'mark' was used BETWEEN 1900 AND 1918.I find no chips or cracks on this plate. I do believe it had a gold rim. I see some indication of that. It measures 8 1/2 inches in diameter. If you have any questions please ask prior to auction end. If any of my other auctions or store items are of interest to you I will gladly combine shipping. I usually ship within 3 days of receiving confirmed payment excluding weekends and Holidays. I do work 3 12 hour shifts a week on a varied schedule. As a result it may occasionally take up to 5 days to ship. Please contact me with any concerns. I aim to please. I appreciate and thank you for looking.
