I have this chinese coin, but I couldn't find it here on Numista. 

 

On the observe side it says: 

天眷通寶

 

And on the reverse it is blank, as shown in the images.

 

It has approximately these dimensions (I doesn't have a caliper, similar size to other coins I have): 

Diameter ≈ 28.5 mm. 

Thickness ≈ 1.35 mm

Weight, more than 6g

And also, i have this one too. 

It is a Qianlong Tongbao, but it have ≈ 21mm of diameter.

Looks like Eastern Xia that is not in the catalog, seems there is only 3 known and would value millions. Not sure if is fake or not.

Seems there are a large variety of diameters, since was cast made, in the examples there are with 22mm

So, the ideal would be for me to have it authenticated by NGC/PCGS, only then would I be able to resolve the doubt that it is genuine. But since they require a 1% fee of the coin's value, I don't think that will happen any time soon. 

 

Thanks for the help!

NGC does not graduate cast Chinese coins

Read the link provided by Geison :

Eight years ago, a group of twelve people from the Shangdang Coin Society went on a "trip to Longcheng" and had the honor of observing the coin treasure "Tianjuan Tongbao". At that time, at the "Sanjin Folk Ancient Coins Exhibition", a "Tianjuan Tongbao" was extremely dazzling in the glass display cabinet in the center of the hall - it was covered with green marks and the whole body showed the "old and aged" appearance of ancient bronze coins. The coin industry calls this form "wide open", "goods at first glance", and "real at first glance". This "Tianjuan Tongbao" can be said to be a great treasure among ancient Chinese coins.

If you really want to get them graded, you could try GBCA, CCGA  or ACGA. All these three companies specialise in grading Chinese coins. I would go with GBCA if I were you though as they are more well-known. Source: I worked at an auction house and the Chinese cash coins we accepted were mostly graded by these firms.

This coin is supposed to be one of the rarest cash coins but there is a chance this may be genuine. I will attach a link to a few pages here and you can translate them.

I've been doing a lot of research on this. I recently received a batch of several cast coins from a gentleman. It came in a old bag. There were a lot of coins, Roman, Greek, Russian, Chinese, Japanese. I'm still sorting them out. Had some gold too.

 

I was very surprised by this coin. Of course, we always thought it is a fake. But it's worth the risk. 

 

In my research I also came across GBCA as the top choice. 

 

Thank you very much for your attention!!!
