Both looks odd. Do you have photos of the edge of the coins?

Second is definitely not genuine.
First coin isn't that clear cut. Highly counterfeit coin that NGC has noted. The patina looks a bit odd.
Unfortunately when you are dealing with smart crooks that potentially read such forums like this and improve their 'products' - one cannot give out too much tips.

@gxseries Thank you for your input. If you don't have a problem, we could talk with private messages and compare notes, since I have many observations and remarks that I would like to talk about. If you are OK with it please send mean an email from your part, since I am a new member and don't have permission to send.
For the rest of the forum members, more advice and comments are more than welcome for the current topic.

I've always said, a big part of knowing whether the coins are real or fake is the person you bought from - if you bought the coin from a reputable dealer or auction house,
high chances are they are real but if you bought from some sketchy stranger at the local market then less chance of it being real.
But there are no absolutes, as I have bought real Chinese coins from a market before with the seller claiming they were fake! It's just whether it's more likely or less likely.

@Numister Yes, I agree. Buying from a reputable dealer usually saves you from a lot of hassle. I bought these coins from a local aucion house, which doesn't specialise in coins. However, I bought them for a small price and mainly for a educational purposes, as well as the off-chance that there might be something to them.
Regarding your second point, you are correct, since I have noticed that many Chinese coins can incorrectly pass as genuine and vice versa. I think even reputable dealers or auction houses may have a hard time with high-end counterfeits.
Concerning the coins I have posted in this topic, do you have any input regarding their authenticity?

Based on pics, some parts look right, others less so.
I concur with gxseries's comments.

I collect and document fakes of Chinese coins and these look like the ones I have.
I doubt they would test to be good silver which should be the very first check instead of depending on photos.

@ Numister Thank you for your input!
@ Albert Yes, I agree. I will have them XRF-tested within the next week. When you say "good silver" do you mean that there won't be any silver in them or that it may be less than it's supposed to? However, I wonder, how is it possible to have correct measurements and weight and not have a certain material, i.e. silver. Of course you could argue that it is indeed a counterfeit made of silver or a counterfeit with a material of similar properties. Since you said that you collect and document Chinese fakes, could you please share some information on them (measurements, weight) or even some photos?

One of my albums illustrates common frauds, flubs & faults seen on such coins.
I see matches here.
Proper diameter & weight may be obtained using wrong metals, but perhaps the thickness could be wrong (maybe / maybe not).
XRF has value, but a properly composed magnet slide, suspended N-52 magnet, or Specific Gravity check can weed out fakes where XRF is not available.
I know the magnets can lead to false conclusions, so go to an SG check if such a case.
I would bet an SG value for these coins would be a 7 or 8 number instead of a 10 or 9 number

@Albert Thank you, very useful information! Which of the two methods mentioned do you think is superior, Specific Gravity (SG) or XRF? Is it possible that an XRF analysis isn't conclusive and takes into account only the surface material or this is a very unlike scenario because a coin is too thin?

I have no XRF so I rely on other tests to determine if silver or not.
In this case XRF would work well showing no elemental silver.
SInce I do not have XRF, my suspended N-52 magnet would show no diamagnetic reaction.
My SG test would show the alloy could not be good coin silver.
I'd skip the gloved finger protection, the coins are not authentic.
I was paying a dollar or two when I was accumulating my collection of fake Chinese.

The counterfeiter likely will not strike any fakes with actual silver alloy, there would be no profit margin, so a XRF device would easily detect it. I'd like to find out how deep of a surface does a XRF device read?
