Sori Yanagi for Tendo Mokko

Thank you for your time.

• Yes i've already seen and there is a lot of price difference ... i'm in Portugal.

Active members of this forum generally avoid assessing values or offering monetary appraisals. The reasoning behind this practice is obvious as markets are so variable.

Unless a piece is either very rare and highly sought after or unique (your stool is neither), condition means everything to buyers willing to pay premium prices. In the end, anything is worth only as much as you can convince someone to pay you for it.

Cool stool, BTW. Best of luck!

Looking at auction results can give you an idea what things sell for.  There are about 16 listings for this stool on Liveauctioneers and the price range is pretty wide, but if throw out the "outliers" I think you can get a decent idea.  Age, condition, and materials are always factors, with the earlier rosewood models fetching the highest prices from what I saw.
