Awesome initiative!
I'd also like to direct everyone who needs to add Chinese lettering to their coins' lettering entry to this site;
http://ce.linedict.com/dict.html#/cnen/home
The drawing feature has been instrumental in helping me get many characters into text to be put in the text box in the past.
Anyway, I'll try to demonstrate my Chinese skills, and if I fail Lolly can take the job up and tell me how I did
Subha; the central characters on that coin, stand for 'Copper Coin of the Great Qing';
the two characters on the left and right 'go together', but I only know the one on the left is 'section'
the string on the bottom is the denomination, but I'm unsure what half of it directly translates as; the last 3, or rather the first 3 characters (since old Chinese is usually right to left) says 'Ten Cash'
Reverse characters on top say 'Made in the reign of Emperor Guangxu'
nthn;
I recognize the word stone in the lower part of your coin's Chinese; and the upper two characters mean 'president' I think. Not sure what the rest could be without using some kind of translate, which I feel would be cheating here.
