Came across this in some bits that I bought. . It looks like it is a 1 Yuan- Yuan Shikai. 1914-1921. It has a diameter of 39mm and 2mm thick and weighs 20g ( this is the bit that puzzles me) as if it was genuine I thought the weight should be greater. So am I correct or is it something else ? A fake/counterfeit or another denomination ? Any help appreciated. Thanks Brian.
