Is this Boo-fu mint-mark on Guang Xu coin? [solved]

Hi to all



I have a Chinese coin that I identified as Guang Xu 1 cash coin:

But I am a bit confused with mintmark. it looks like Boo-fu one, but the bottom part of right mintmark is a bit different than on other Boo-fu ones. Can it be a variation of some sort?

Examples of Boo-Foo mintmark from various coins:

I think a small cast default.

I think you right. And this list shows that there are variations in Fu. There is also open Fu on 22.1330
