Page 28 - ... uniform lines of the lathe-work which the counterfeiter cannot reproduce to save his life. This machine work is therefore the safest ear-mark there is for detection purposes; but it must be used intelligently. In examining this work on any suspected note, it is a pretty safe way for the examiner to begin at the centre of the curvilinear figures and then gradually follow the lines around the circles, one within another, carefully searching for any special defects and for the discovery of any irregularity...
Page 35 - Counterfeit lathe work can be detected by the blurred and dotted appearance of the lines where they intersect each other. These defects, which might be overlooked, can easily be detected by beginning in the centre of the curvilinear figures, and gradually following around the circles. On many counterfeits actual work of the lathe is to be found, the figures being made up of small circles, which would readily be detected by an educated eye.
Page 43 - Liberty;" a large star forms a brooch, clasping her drapery ; her hands are extended towards fasces planted on a rock and entwined by wreaths and belts, the latter bearing "The" and "Union," at the right
Page 25 - THE ROUND HAND. This form of lettering is observed in the legend on the Bank Notes (which is the same in all), and in the words " Will pay the bearer." The curves and hair lines are drawn with positive accuracy. There may be a difference in the style of letter, but this will not change the precision of the work, as may be seen by comparing the curve's and lines of one with those of another.

Clear skies are also usually formed of fine parallel lines. When cloudy or heavy skies are required, these lines are made to cross each other. Sometimes sky is formed of several broken etched lines. Great care should be taken to...
Page 22 - ART OF DETECTING COUNTERFEITS, WITH RULES FOR GENERAL GUIDANCE. The art of detecting counterfeits consists in becoming thoroughly familiar with genuine work, and in bringing any new or untested bond or note to a critical comparison with a plate known to be genuine. It will be seen that this method is precisely the opposite of the old system, which made the counterfeit the basis of investigation...
Page 24 - In counterfeits the features are usually blurred and expressionless, the eye is dull, the arms, feet and hair imperfect, and the dots and lines which form the face and the exposed portions of the person are large, coarse, and uneven. A careful study of vignettes is recommended to all who desire to become experts in the art of detecting counterfeits.
Page 36 - The arms, hands and feet are invariably poorly drawn. The dotted lines or stipple work denoting the flesh are coarser and darker. The shaded sides of the arms and legs are generally very dark. The fingers and toes are coarse and clumsy, seldom fully developed, and oftentimes drawn to a point, in both cases lacking the animation of the genuine. The drapery is...
Page 23 - Notes consist of vignettes, -scrolls, borders, counters, corners, marine views, war scenes, etc. On genuine plates these devices are perfectly formed and symmetrically grouped. Such, however, is not the case in counterfeits ; and no matter how near counterfeit work may approximate to the genuine, "a close observer, with an ordinary microscope, and with the illustrations in this work from the genuine plates l)efore him, may at once detect the imperfections and irregularities which distinguish the...
Page 30 - ... a fibrous surface. When examined with a microscope these fibres have the appearance of coarse black hairs, of all conceivable lengths and shapes, scattered promiscuously, regardless of regularity, over the entire surface of the bond or note. A narrow strip of bluish color, termed "localized tint," extends across the entire note, and is tiie result of a second process.
