Hi, I just got back from China. On the very small market I managed to buy 3 coins that seemed very legitimate. They weight around 27g each and are non magnetic. I would appreciate if someone could tell me how to check if they are really silver.   |

that is the key word.. seemed..
most likely fakes..i know little about asian coins, but they do exhibit the fake patina, that is associated with their fakes.

Ask yourself this question: "Why do all three coins have the same type and color of toning?

Good point, westernsky. They look a lot like what I see from Chinese sellers on e-bay, in terms of color and patina. Mass- produced forgeries flooding the market.

Supposing you have a digital scale that weighs out to a hundredth of a gram (such are relatively cheap and available), you should be able to make a general determination as to their specific gravity.

The edge and its modern look and raised dots under a magnifier in the fields illustrating their cast die transfer process. Although the most common alloys are Fe/Ni, German Nickel and sometimes debased silver they do make them many times to regal weight, apply artificial toning and simulate worn edges as in a bin roller. In my new book Forgotten Coins I do an A-Z attribution on Chinese Forgeries. Yes ... they have that patina look from these types of alloys mentioned here. DULL. Faked toning. Modern Edges - raised field dots.

I 100% guarantee you that those coins are not genuine!
No doubt whatsoever. I am certain. A cow can turn into a horse at will before these are genuine.

Your coins are obvious fakes- but that was not your original question.
You want to know how to check if they are silver.
I would suggest you search online for Chinese Silver Testing or just ordinary home tests that can be done to check for silver.
I think there may be 14 or more or less helpful hints on how to check for coin silver. Some of these are videos and some sources just have a list of testing methods.
I'll give you some tips on what I think:
Diamagnetic=no
Bleach spot= probably no
Ice melt= fail
Sliding magnet= fail
Suspended magnet=fail
Density= 7 or 8 but no way possible to be 10
Visual= multiple devices and details all around coins will be wrong.
Ping test= if they do ping the pitch will be too high or too low or too short duration.
