The work of counterfeiters can never equal that of the makers of genuine notes, whose skill and facilities for producing the highest grade of work known to the art, are the best that the world affords.
Unless one is somewhat learned as to the quality of engraving, that he may be able to distinguish a fine specimen of the art when he sees it, he is likely to become a victim of the counterfeiter's operations.
LATHE WORK.
When the genuineness of a bank-note is doubted, the Lathe Work on the note should first be closely scrutinized. The several letters of denomination, circles, ovals, and shadings between and around the letters in the words, etc., are composed of numberless extremely fine lines--inclusive of lines straight, curved and network. These are all regular and unbroken, never running into each other, and may be traced throughout with a magnifying glass.
Without the skill or machinery, by which the genuine is produced, the same quality of work cannot be done. Therefore, in a counterfeit, the lines are imperfect, giving the paper a dull or hazy aspect, that may be all the better appreciated by comparing it with the genuine. The lines in the counterfeit will be found now and then irregular in size, and broken: not uniform in course, sometimes heavy, sometimes light: no two stamps or dies on the same note being exactly alike.
The fine, uniform, shade-lines, with which the letters on the genuine are embellished, are wrought by a machine that cannot be reproduced by counterfeiters, nor used for other than legitimate purposes, by authority.
GEOMETRICAL LATHE.
The fine line is the characteristic of the various and beautiful figures which are seen on a genuine note. This line is produced by what is called the Geometrical Lathe. The patterns made by the geometrical lathe are of every variety of form. They are not engraved directly upon the bank-note plate, but on pieces of soft steel plate, which are afterwards hardened. The impressions are then transferred to a soft steel roller, which, in its turn, is also hardened, and the impressions remain there, in relief. This roller is then capable of transferring the same designs to the bank-note plate by means of the transfer press.
In counterfeit engraving, the design is made directly upon the plate, and not by transfer, as in the production of plates for genuine notes. The essential difference between the two methods of production is, the counterfeit is made by hand, and is inexact and imperfect, while the genuine is made on geometrical principles, and is therefore exact, artistic and beautiful.
In all the government issues the geometric lathe work is liberally used. This should be studied carefully, as it constitutes the chief test of genuineness.
Fine lines, of unerring exactness, never broken, are seen on the genuine medallion heads, or shields, upon which the designation of the note is sometimes stamped. This nicety cannot be given by hand, or with the use of imperfect machinery. By close scrutiny the lines will be found to break off in the pattern, or appear forked, irregular in size, and not well defined throughout.

On most counterfeits the vignettes are not well engraved, and the portraits have a dull appearance; the letters are usually wanting in clearness; the printing is sometimes faulty, by which some features of the note are obscured.
RULING ENGINE WORK.
In Ruling Engine Work, as it is called, the fine line is present, also. The engraving is produced and transferred in the same way as the geometrical lathe work. In this they are parallel and not in circles. Those which constitute the shading of letters are so fine that they form a perfectly even gray shade. They may be printed so that the shading will appear darker, but the aspect will be uniform. The spaces between lines are exact, whether the lines be horizontal or diagonal. The lines are also made crooked or wave-like, not absolutely parallel. Ruling engine work is generally used for shading of names of banks, and also for the names of town, state, etc.
