Contemporary or Modern Counterfeit?

I've narrowed it down to this N#1133, but the dimensions and mass do not match. 

Mass is 3.31 grams.

Diameter is 21.4 mm.

Thickness is 1.2 mm

Edge is plain.

Anyone care to speculate as to whether its a contemporary or modern counterfeit? I found this in a bag of foreign coins that a relative gave me. If it is a contemporary counterfeit, I'll probably hang on to it. If its likely modern, its going in a small coin bag that I use as a paper weight.

My opinion is that it is not counterfeit at all. The Hartill link is correct but the actual code would be Hartill# 22.224, it looks like the vertical stroke of qian is straight. Because there are so many variations the mass and diameter varies a lot too.

Thanks for spending a bit of your time looking at this.  I'll check out Hartill# 22.224.

I agree with Ollisaarinen, also due to the fact that there were so many of these cast and they are available for so cheap that there is no real incentive to fake these other than feng shui, which I do not believe your coin is.

Thanks for the input. I was leaning towards a contemporary counterfeit if it indeed was such. I agree it's not something that would be worth counterfeiting after it ceased being official currency. 

I read in a couple of places that sometimes these coins would be manufactured by non official sources with a reduced mass/size looking for an arbitrage trade in the difference in the metal content. 

Looking deeper at some examples from graded coins or even coins from what appear to be reputable places, I see the mass is mostly a moving target. It probably doesn't help that apparently the mass and composition of officially minted examples of this had stipulated regulatory changes over time. So, I'll be more careful trusting the mass and dimensions listed for coins of this type.
