The expression “not for money, marbles, nor chalk” means: Not for any consideration whatever; absolutely not; utterly incorruptible.
Although “marbles,” in this expression, could be taken to mean “slight value,” with “chalk” indicating “no value,” we think it more likely to be a slight mispronunciation of meubles, a term of French origin used both in France and England to mean “personal property.”
Thus the expression would literally mean, “not for real property, personal property, nor useless property.”
