New collector with questions about fakes.

Hi all,  
I've only been collecting for a few months and am trying to get coins from every country . Next up on my list is China. I'm interested in a few coins, but I am trying to be aware of fakes. I'm interested in these coins specifically. Any insight from a veteran member or someone who has more expertise would be greatly appreciated. Thank you in advance!

If you get coins from china make sure you get a certificate of authenticity signed by chairman mao 

Hello! I think the coins look fine and are not fake.

hello,

you can compare yourself by searching chinese coins, filters:

year 1919

face value 20

I've no idea about the second coin, perhaps the image search will help you.

Hello

The second one is Qian long tong bao

And  genuine
