Finding the Value of Danna Seizan Fine Japanese China?

I researched again and although there are a couple of sets available on line, they are not the same pattern and all have less pieces, plus there is no way to tell the condition. Also, I have found no sets that were actually sold in the past 12 months.

If you live in a larger city there may be a local shop to ask but generally this type of free appraisal is worth very little unless they are experts in this field AND/OR they are not interested in buying your set.
Appraisal and asking price are generally just that - a price - maybe for insurance purposes the price is good but when it comes to actually selling something that is an entirely different thing. If your china is actually worth a large sum you may have to take it to a real auction to get the true value and then it is a risk.
Trying to sell on line is very difficult unless you are showing the set as "pick up only" and no shipping. Selling a set on line may take weeks/months/years (yes - years) before an interested buyer comes along. There is a lot of luck in selling such a specialized item - anywhere.
On line appraisals are inexpensive and generally done by experts in the certain fields as they do this in their spare time.
Hope you find what you are looking for.

Looks like a beautiful set and 90 pieces is almost unheard of but there does not seem to be very much information available. Which could of course mean the value might go either way - high or low.
Since you have already looked at the auction sites and Replacements then it seems you may have to go with an appraisal. You can find many sites on the Internet that offer appraisals but the actual cost can vary widely.
