Help with authenticity

Hello,

I am wondering if the following coins are real. The guy that is selling them I have bought many coins from in the past and is a trusted seller, but with Chinese coins even the best can be tricked. The pictures aren't that good because they are from my phone.

Coin 1:


Coin 2:


Coin 3:


Coin 4:


Thanks in advance for any help. If they are real could someone provide an idea about the value of them.

Regards

Questions about authenticity require sharp pictures (without plastic pockets) and weight at least. Sometimes rim photos and diameter are also important.

Without them, if I were to guess, I'd say that 20 cent Kwang-Tung coins look OK to me.

They look real in this resolution. The Republican 20cents aren't worth that much anyway.
