I think the person is suppose to be Yuan Shi-kai
Correct; Yuan Shi-Kai from the (brief) period he had himself proclaimed emperor.
I have a copy of this coin, in similar crude style; It was one of several fake crown-sized coins found in a bulk lot of mixed world I bought at auction once. Silver content: zero. The silvery layer (whatever it was) has partly worn away, showing the brassy core. Mine is much lighter than a genuine silver dollar (only about 15 grams):

the fake costs US$5 for the learning process. The original is about?
Would you happen to know silver percent content? thanks again
I don't think you could buy a genuine one in reasonable condition cheaply.
this one on CoinArchives slabbed by NGC recently sold for $4500. One in the condition svslav posted would probably cost you $1000 or so; one in similar condition to "yours" would probably be about $100.
Standard silver content for early republic-period Chinese dollars is .890 fine. Of course, yours probably has no more silver in it than mine does.
