It was made for export to the North American market between 1891 and 1921.

In 1890, the American McKinley tariff law decreed that all goods made for export to the U.S. had to be marked with the country of origin.
Japan at this time chose to use the word Nippon. In 1921, the U.S. government decided Nippon was no longer acceptable. From then on, goods were marked Japan.

This provides today's Japanese porcelain collector with an easy dating guide.

SPECIAL NOTE: The American Society of Appraisers estimates that only 25 percent of the 120,000 appraisers in the United States belongs to one of the major evaluation societies. Such societies establish codes of ethics by which their members are required to adhere. In addition to a code of ethics, the appraisers are tested for their expertise.
OR:
Refer to the Yellow Pages in the Telephone Book under "Appraisers" of "Antique Dealers."
WHAT TO DO WHEN YOU LOCATE AN APPRAISER:
Review their credentials
Verify their membership to an appraising association
Request references
Determine appraisal fees
Request a written contract which outlines the following items:
The scope of work
The delivery date of the appraisal
The appraisal fee
The objective nature of appraisal findings
A statement that the appraiser cannot act as an advocate or negotiator in disputes over appraised goods.
Once you can establish the history of your pieces and they have been authenticated, i do not believe that you will have any problems selling them at any of the best of the above Auction Houses. The historical aspect of these sort of things can far exceed the normal and nominal fees usually obtained, unless of course they are also from an important maker,artist etc.
If you have the time, you could also go to your local library and select a few different books. There are several available and you'll be able to compare information and prices.
Go to the book store in the antiques section. I often find books that help in identifying the piece, style and maker.

Hope this helped.
Cheers!
