Please Help Me Identify This Coin (If It Is A Coin)

My initial thought was a cast cash of the Qing Dynasty in China, where the reverse has similar markings. However, they aren't on the corners of the square, but rather the sides and there are four (different) characters on the other side. I'll keep looking, but in the meanwhile can you please confirm that it isn't attracted to a magnet? I want to make sure that we are dealing with a copper alloy rather than iron. Thx.

So nobody has an opinion about whether this thing is a coin or not?

Thanks joewobblie, I'm starting to think that way too.

It hasn't been cast in the traditional method of making cash-style coins - but it's been designed to kind-of-look like it was cast.

This, combined with being made of iron, points me toward it not being an official coin. My best guess: a "funeral coin", designed to be thrown into a funeral fire.

It seems to have the same design on both sides, which also points towards a non-monetary function. I can't tell if the script is Manchu, Arabic, or just random squiggles intended to mimic Manchu. But the lack of Chinese characters implies to me it is not of Chinese or Chinese-diaspora origin. Perhaps from somewhere in Southeast Asia.
