Counterfeits upon the old-fashioned plates, “Perkin’s stereotype plate” and others, all that contain any transferred dies, the pattern white upon a black ground, can be detected by the imitation of transferring. Diagrams E, F, on page 16, also diagrams, L, M, will illustrate this principle. In the genuine it is machine waved-ruling transferred from dies, while in the counterfeit this is imitated by engraving the black spaces immediately upon the plate itself, and attempting to make it fit so as to have the appearance of being transferred. L represents the genuine, (though imperfect,) M represents the counterfeit. There are four out of the seven Rules that will apply to the old fashioned “Perkin’s stereotype” and most other old-style plates, viz: the 1st Rule, or Transferring; the 5th Rule, the Lettering, especially the mass of small lettering, “One Dollar,” “One Dollar,” in the body of the note; 6th Rule, the Signatures and filling up; 7th Rule, Paper and general appearance.
