This is a small bowl at 3.5 cm in diameter. It has a blue rabbit looking back at the moon, assuming this is the moon rabbit or jade hare. There is markings within the designed picture and japanese markings on the back. I inherited this and it came to me as a set of 3, assuming one is missing. One of them looks like someome has appraised before. There is a sticker on jt stating circa 1850. Trying to find any information on its history, age, and worth.
