Recently I came across the expression "coarse hand" and couldn't find its meaning. For example,
— Can you read?
— No, only coarse hand.
What does this mean?
Edit
This is a term Twain used in The Adventures of Huckleberry Finn
I was a good deal astonished, but when I got my breath I asked her what the paper was about, and she asked me if I had read it, and I said no, and she asked me if I could read writing, and I told her "no, only coarse-hand," and then she said the paper warn't anything but a book-mark to keep her place, and I might go and play now.
