Hey everyone, What do you guys think about authenticity of the lang bar below. It is underweight but looks like the sides have been filed down a lot (the incused circle/square marks on the top and bottom are not clearly visible anymore). Sorry for the bad lighting, the bar is much darker in person. Weighs = 27.64g Dimensions = 1.3 x 0.7 x 4.1 cm Year = 1802-1820 (Gia Long reign) Value = 1 Lang
