Hi,

Are the pieces marked at all? Typical ginger jars in Satsuma or Kutani style (both are regions, not specific companies) sell for $10-20, but yours does appear very well made so if its from an identified artist it may be worth a bit more. I would also estimate yours to be from the 60’s, so they aren’t quite old enough to be highly sought after yet, but hopefully down the line they will become more highly collectible.
