A piece of money, worth nothing.

"But I felt that the kiss was given to the coarse common boy as a piece of money might have been, and that it was worth nothing." (Dickens 121).

This is an odd quote to be coming from Pip, who seems to be so in love with money. He says indirectly here that money is "worth nothing," just as Estella's kiss was. This is probably Dicken's point of view, as is shown in the moral of the book. Money has no real value, no intellectual or personal value, and is "worth nothing" to him. Dickens says it is bad to yearn for money and seek it out.
