This is a magnificent Chinese eastern Han dynasty mirror. This puts it right around 2000 to around 1800 years old. this came from a large private Chinese mirror collection. Due to bronze disease and corrosion on it I do believe it to be genuine as it is very hard to fake bronzes disease in this type of corrosion as it takes hundreds of years to occur. Take a look at all the photos to see general condition, dimensions, weight. It has a protective handcrafted wooden box specially made for it as well.
