Dear Diane,

Thank you for contacting Mearto with your appraisal inquiry. The presented object appears to be a irononstone serving platter with a blue transferware decor depicting an traditional Chinese porcelain decor. It has the lenght of 14 inches and is hallmarked by Buffalo Pottery Semi-Vitreous with the year 1903.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 30 to 60 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
