Chinese bronze

Hi, I tried to find this coin, but I can't find anything about it. First, I hope it’s a genuine Chinese coin, but I’m not sure. Its diameter is 43mm and its thickness is about 3mm. The material is Bronze. Thank you for every comment and every help !!

The first character is more than 11 strokes, what the hell is this "Tong He" ?

That certainly seems like a strange inscription. Tonghe (統和) was used under the Liao dynasty, but those coins are Yuanbaos rather than Zhenbaos (珍寶), and they only come in a 1 Cash denomination, as far as I am aware...

Thank You very much! What do You think, is this coin real or replica?
