Thank you for submitting your item for appraisal. This appears to be a chinese mostly transfer printed porcelain egg, decorated with japanese motifs in the tradition of Satsuma ware. Such reproductions have been around since the 1990s. The egg shape is a chinese invention, the moftifs follow the traditional designs of japanese Satsuma ware. The estimate is based on similar sold at auction if correctly described, wrongly described as "antique" they sell in the 40-80 USD range.
