Identify Chinese coin.

Dia. 1.778 inch  Weight is approx. 36 grams. Thanks for the help.

I fixed the first image.

Copy/replica of this N#290466

For my own information, how do I recognize that this is a replica/copy? Thank you.

Details are off. Here's a couple of obvious ones.

But mainly it should be 40 mm diameter and yours is 45 mm.

Thank you for your assistance.

It's quite funny that the copy is from a better quality die and strike than the original.

True. Here's NGC's picture. Probably should have use it to compare.
