Cover art for Silver Coin lyrics by Angus and Julia Stone

I interpret the song as being about a boy who is in love with someone he can't have. He sees her on a silver coin - i think this is eluding to her being like a queen, so she is above his class. Also the line "im in the days of throwing rocks" means he is probably young, a teenager.
