China Ming Dynasty Chong Zhen but which variety

I have this coin:


Weight is 3,59 g, diameter 22,55 mm. I know this is Ming dynasty Chong Zhen coin, but I can't find Hartill code. Primaltrek web-site says that this has only mint marks on the reverse side, other side is plain, as mine is. I'm pretty sure this is not fake, bought from trusted place. This has square head and two large dot tong. Please help me to identify this and I would also like to know the apprx. value.

show the other side

If there is no special mintmark, then it is common (not rare) and around 10 RMB in china market.

I can't tell what specific type is this one in terms of Hartill code, I think you better upload also the reverse side to ensure it is nothing (even a very small dot).

Here is the other side.

Which edition of the Hartill book do you have?

My Hartill is 2017 edition (second edition).

up.
