My friend that died, his wife was from Italy, and she had antiques sent over to her.
Thank you for submitting your item for appraisal. This appears to be an italian majolica rococo revival late 19th century mirror. The crown symbol as a trademark was used by several manufacturers, e.g. Ceramiche di Bassano, which I think is most likely correct comparing it to other products of this company. The mirror pane surface appears to be very even, therefore dating to after 1880. The estimate is based on similar mirrors actually sold at well advertised auctions. There is no measurement for the sentimental value you might attach to the item.
