Fake Chinese coin?

I suspect this coin is probably a good fake. I used a magnet and there was a miniscule reaction to it. The coin is 39mm and weighs in at 37.07 grams. I lookin the Numista catalogu which does list a conterfi exampl but the weigh and size is off by a lot. Love to hear your thoughts about on it.

I just read a post on here. It's a totally fake as there is only one “real” coin in existence in China. The question is then whether this coul be considered a good fake? Lol
