This blog has written about “yo’uhen tenmoku” bowls in the past.
There is a Japanese TV program “Nandemo Kante’idan” – similar to our “Antiques Roadshow” where viewers can bring their item to have it evaluated by professionals.
According to a recent Japanese news story, a new “yo’uhen tenmoku” bowl was discovered and was valued at 25,000,000 Yen (approx. $213,000). Until then, there were only three bowls known to exist – and they are all designated as Japanese national treasures. Some appear to think the valuation was too low.
The bowl was part of the lot purchased by the owner’s great grandfather during the Meiji period from a well-known samurai family as part of the compensation for the family residence’s construction work he was performing for the family.
