Dollar coupon size regardless of denomination and version are 156 mm x 66 mm. Front side pattern color is black. On the back of the main pattern for the building, the main color is green, but different types of color is slightly different, such as the 1934 version of the back is dark green; the 1950 edition is on the back of the grass green; after the 1963 edition version are dark green. Counterfeit characteristics of dollar bills (a) special paper: paper bills for senior white paper, mainly made of cotton, hemp fiber is made. The paper is tough and scraping and has no fluorescent reaction under ultraviolet light. (two) fixed portrait watermark: in 1996, the US dollar paper added the same watermark as the face portrait. (three) color: red, basket fiber from the 1885 edition, the greenback paper joined the red color fiber wire basket. From the 1885 edition in the 1928 edition of the greenback, red color fiber is the directional cast basket, the middle basket of red, silk fibers in banknotes, forming two narrow bands from top to bottom. After the 1929 edition, the red, basket, and colored fiber threads in each edition were randomly distributed throughout the bill. (four) text security line: from 1990 edition, $50 to $100 in each denomination (portrait left) joined a full text security line. There are alternately printed letters "USA" and "Arabia" or "English words" in the security line. In 1996, 50 and 20 dollars were added to the security line, and the American flag was added. The 1996 version of the US dollar's security line is a fluorescent safety line, showing different colors under ultraviolet light. 100, 50, 20, 10, and $5 are red, yellow, green, brown and blue, respectively. (five) intaglio printing: the portrait, construction, border and denomination numbers of the back of the dollar are all engraved and intaglio printed. Touch your hands with a distinct bump. Because the intaglio needs high pressure, the ink has the diffusion phenomenon, the ink overflow, the line belt, the hair, the tooth, this is the gravure printing important characteristic, needs to use the magnifying glass to be able to look clearly. (six) letterpress printing: the bank stamp on the US dollar note is printed in letterpress, and the touch of the corresponding part of the back of the banknote can be felt with a touch of the Wacom. (seven) fine print: the 1996 edition of the dollar is in the background of the portrait portrait and the back of the building is designed with a thin line. The design has a strong copy proof effect. (eight) gravure microfilm text: 1990 edition, by adding a gravure microfilm text organization in the dollar link figure edge, microfilm text to "THE UNITED STATES OF AMERICA", with a magnifying glass to see. The 1996 edition of $100 and $20 respectively in front of the lower left corner of the denomination number increased "USA100" and "USA20" micro text, $50 is on both sides of the front lace add "FIFTY" on the microfilm text. (nine) crown word number: US dollar, the front of the bill is printed with two sets of horizontal numbers, the color is emerald green. The 1996 edition of the previous $crown word number by a crown word, 8 digits and a suffix letters, 1996 edition $add a crown word, represented by the year. (ten) light denomination number: 1996 edition 100, 50, 20, 10 dollars in front lower left corner with denomination digital optical variable ink printing, is green in the observation and the nominal vertical angle, the angle of money into black. (eleven) magnetic ink: Dollar positive gravure ink with magnetic, magnetic detector can be detected magnetic. The authenticity of the dollar We must first face features of each version and the authenticity of the security features of a comprehensive understanding and grasp, and then by direct comparison method (see, touch, ears) and instrument detection method for identification, which is often referred to as a two touch, three listening, four". (a) look at the color of the face first. One side is really the main color is dark, the back is dark green (1963 version version), crown word number and library printed for the emerald green, and with luster. Counterfeit color is not pure enough, the color is also dim; secondly, is to see the face pattern, line printing effect. The banknote pattern of the banknote is made up of dots and lines. The lines are clear and bright (some of the lines have slight ink absorption, which is normal), and the pattern level is characterized by rich facial expressions and human eyes. False money line virtual, flowers, have lost points, lines, patterns, lack of hierarchy, people look dull, dull eyes. Again, look at the light change denomination figures, 1996 edition of more than $10 real banknotes are light change denomination figures, change observation angle, you can see from green to black. Counterfeit or no color effect, or color effect is not obvious, there are differences in color contests notes. Finally, look at the paper. Watermark and security line. Dollar paper has a reticulate, clear texture, color of irregular fiber distribution in the 1996 edition of the American dollar paper; paper joined the same face portrait watermark, watermark level rich, strong stereo sense; 1990 edition of more than $5 banknotes in the text line, the line is smooth, clear text line. Counterfeit paper, or no mesh, or mesh is messy; watermark patterns lack of hierarchy and three-dimensional sense of security lines, text lines fine uneven, font deformation. (two) touch one, touch the paper. The paper is very smooth, smooth and has good toughness. The counterfeit paper is relatively soft, very poor, some thin, some thick, smooth degree or higher or lower. Two is touch gravure feel. The real money is king on the back of the main pattern and the frame adopts emboossing, touch has obvious concavity. Counterfeit or flat offset printing, there is no gravure feel. Or even if the gravure printing, its version than the real note to shallow, gravure feel and real money compared to still have a certain gap. (three) listen to hand shaking or finger moving paper, the real money will make a crisp sound, the sound of the note is more boring. (four) measurement is to use a magnifying glass to observe gravure printing. The 1990 edition, more than $5 banknotes printed gravure microwriting, observed under a magnifying glass, the text legible. The microfilm of the note is ambiguous. Two is to use magnetic testing instrument to detect magnetism. The black gravure ink of real banknote contains magnetic material, and it can be detected by magnetic detector. Counterfeit or not magnetic, or magnetic strength, distinct from real money. Three is to use UV light exposure. No fluorescent reaction of banknote paper, counterfeit some obvious fluorescence reaction; the 1996 edition of security line will have $fluorescence bright, counterfeit security line some fluorescent reaction, some even fluorescent reaction, but the brightness is dark, the color is not normal. Simple identification of true and false dollar 1) paper. It is dollars to cotton, hemp fiber as raw material, through a special process made of high-grade milk white paper notes, tough texture, crisp, gently shake, "pops" sound. Paper contains red and blue fiber silk, some can be seen faintly, some floating on the surface, such as with fine needles to pick, the fiber line can leave the paper money. Fake dollar general paper is poor, not stiff, and easy pilling, tough texture degree is bad, often break easily folded. Most counterfeit paper red, blue fibers, imitation silk fiber not only in printed on the surface of paper separation. Refined banknotes, although there are some red and blue fibers, can also use the fine needle pick, but fake fiber material and the real one with different. Under the ordinary violet lamp inspection, generally no fluorescence reflection. 2) plate making. True dollar positive character image, text, lace are artificial carving gravure printing plate, and digital printing is a convex line. The back view and lace are gravure. True money printing lines, clear lines, the image of the level of deep and clear, touching the imprint by hand, there are obvious concave and convex feeling. The dollar is generally false photolithographic lines, rough lines, hand lines imprinted no concavity. The use of counterfeit refined touch slightly raised a sense, feeling is not obvious. 3) ink. True dollar positive character image, text, etc. with black lace gravure ink containing magnetic material, with sheen, pattern on the back with dark green ink printing, bright eye-catching. On 1996 after the release of the new version of the dollar, but also to look at the number of color change ink, from the front view is green, lean to see black, hand count is clear and tidy. 4) safety wire. In 1991 1990 issued a new $50 and $100 bills, gap between the row and India edge, hidden inside a vertical transparent plastic belt, commonly known as the "safety line". In this article the security, there are pros and cons of alternate micro printed letters "USA" and the denomination numbers straight bills surface is not revealed, Ying ray both sides can see. In 1990 the new false Dollar General safety line, refined version of counterfeit money although also has a copy of a safety line, but not meet the perspective of "USA" and the denomination numbers blurred. 5) check portraits. The $carving is very exquisite, like the combination of point line not only the portrait of the character, and the portrait of the level and stereoscopic effect with structure portraits, skillful carving techniques make the portrait was true to life. All kinds of dollar counterfeit notes have their own characteristics. They are made better and have defects on the portrait. Therefore, to observe the changes in the head line, they seize the key and are the key to timely identification of forged banknotes. There are flaws in refining counterfeit often elaborate portrait lines, and this gap is not easy to modify, to amend the version will have to change. Check the portrait line's subtle changes, Is an important method to identify the counterfeit fine. 6) different denominations of dollars, the front and back patterns are also different. 1 yuan ticket money printed on the front side of the first president George Washington portrait, the main pattern is back on the back of the great seal of the United states. In the past 2 yuan coupons only federal coupons (red base printing company), other securities without this denomination. The portrait is a portrait of Thomas Jefferson, the back of which is the signing ceremony of the declaration of independence. 5 yuan coupons printed on the front sixteenth United States summary Abraham Lincoln portrait, mainly for the back of Lincoln Memorial in Washington, memorial hall is divided into two layers. The text on the two floor of the eaves, visible with a magnifying glass. The top 15 states, the lower 11. The 10 yuan bill is a portrait of Alexander Hamilton, the back of the US Treasury building.
