Except, as you can see at the bottom of the Chinese inscription, this is actually a 20 cash coin, not a 10 cash. So it would be this coin
The mintmark, on this coinage series, is the incuse character stamped into the central disc on the Chinese-language side. "Tai Ching Ti Kuo" is an old Anglicization of the characters #22823;#28152;#24093;#22283;, which in modern Chinese Anglicization are "Da Qing Digou", translating to "Great Qing (Dynasty) Empire". So it is in effect just the name of the country.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
