Most pottery or porcelain pieces will have a manufacturer's mark or signature. Recognizing and understanding these marks can often provide valuable information about the item.

Porcelain Marks

Porcelain marks usually include a company or manufacturer's name or initials, and sometimes the location of production. They can also include specific marks that date the item, designations of the artist who decorated the item, or indications of awards won.

Pottery Marks

Pottery marks can be more complex than those found on porcelain, as they often include the potter's personal mark, the factory mark, and other specific details relevant to the item's production or design. These marks may be impressed, painted, or incised onto the piece.

2. Age: Generally speaking, older dishes, especially those that are part of a well-documented history, have more value.
