There are no marks on one of the cups and saucers. There are different marks on the other two cups and saucers.

Good morning, Christine,
Those marks are very unlike any marks I've seen on Japanese porcelain, and the style of the cups and saucers are quite European, particularly for porcelain supposedly made in the mid-19th Century. I'd be interested to know more about what the Smithsonian said about this - can you provide more information so I can look into these?
Thanks!
Delia

The Smithsonian reference is online. Apparently Commodore Perry was insulted by the quality of the gifts from Japan, and let his crew pick through the gifts. Is there any way for me to upload a PDF from the museum here?

After researching Annie Collins, I see that is not Commodore Perry's wife. It could be a daughter, Anna. OR this is part of the collection that was given to his crew.

Good morning, Christine,
I've looked through the files accessible in the link you provided and don't find a match. Again, these are quite European/Western in look and I am not convinced these are of Japanese manufacture. It seems that the letter was written quite a bit after Perry's expedition - there was such a great volume of merchandize involved in the China and Japan trade that it's possible that these were brought to Japan soon after it opened up but fairly soon afterwards were brought back to the US. Without the Perry provenance, these would be worth less than $100 but the Perry provenance adds some value.

Based on the photographs and information provided, and subject to examination, these are:
A set of three hand-painted and parcel gilt porcelain cups and saucers
Probably Continental, early 19th Century
purportedly owned and descended in the family of Annie Collins, wife of Commodore Perry
$150-250*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you for using Mearto.

Thanks very much

Hello again, I do have something I would like appraised, appears to be pre-columbian art but was bought at an estate sale, and has been in this country since before the UNESCO agreement. It's a bowl, appears to be Mayan in origin, and has marble which has I think is only found in Honduras. It may be a fake, it may be pre-columbian, but I'd like your opinion.

I've uploaded the pictures to the same file that holds the pictures of the cups. Thanks

Hi Christine,
The Pre-columbian item needs to be under its own appraisal as I am not a qualified appraiser in that area and other appraisers can't work off an appraisal I've been working on.
Thanks,
Delia
