No, the US in those days was not big on enforcing copyright laws, sort of like China today, and so many Americans read Dickens' works who never paid him royalties for it.
Dickens hated being cheated and so thought us a bunch of crass money-grubbers -- and that was many years before 1860.
IIRC, Dickens had nothing good to say about us until after the war, his final tour of the United States, he finally saw a different side of Americans and said so.
