Okay, got it.
This very nice silver tea set is Japanese, decorated with a traditional lappet band of stylized lotus leaves, fully marked as sterling silver, and dates to around 1890 - 1912.
The two characters 純 銀 "jungin" side by side in the rectangular cartouche translates as "sterling silver".
This jungin assay mark was used only during the Meiji period 1868 - 1912.
The other two-character kanji mark is:
Little is known of this maker other than his name which is recorded on page 233 of Wakayama Homatsu (Takeshi) ed., Kinko Jiten (A dictionary of metalworkers), Tokyo, 1972,
I would give this set an auction or on-line value (eBay etc) in the range of $3500 - $5250.
It therefore has a full retail value (if you it for sale in an antique store) of at least $10,000. This is also the replacement value for insurance purposes.
I do hope this helps!
Please let me know if you'd like me to explain or expand on any of the above, I would be glad to.
PS. If you go ahead and open a new question for the ceramic set, I'll appraise that for you too. Please put "For Robert S. only...." in the subject line, (and/or select me from the list) and it will be sure to get to me.
