Chinese coin identification

Hello my friends, i have bought these 3 chinese coin online and they arrived today. I was hoping that some of you could help me tell if they are genuine or fake.

Thank you

Next time, please take more focused pictures of both sides of a coin... diameter wouldn't hurt either.

But from left to right, your coins:

They're real; the copper machine-struck, non cash late Qing issues are generally far too common and cheap to be worth faking.

The holder has propably more value than the coins inside
So please take pictures without the holder and compare with the pictuers in the provided links.
They are ineed real, Till now I have not seen a forgery

Thank you for your replies and advises.
I am new here and your sugestions are valuable.

All the best
Alex
