Today we present to you a counterfeit currency made with a laser \u2013 which is one of the modern techniques in the field of counterfeiting. Let us examine it scientifically to uncover its secret together: The currency presented is from my private collection and it is a crown of Queen Victoria with the design known as \u201cWidow\u2019s Head\u201d issued in 1894.<\/p>\n\n\n\n<p class=\"has-text-align-right wp-block-paragraph\">The coin is supposedly made of 0.925 sterling silver, with a diameter of 38.6 mm and a weight of slightly over 26 grams. The piece shown is, of course, much lighter in the hand, and its chain is razor-sharp. It&#039;s also noteworthy that the counterfeiter made it with the reverse side facing up, as is typical of American coins (the opposite of British and Egyptian currency). For these reasons, I assure you it will never fool you if it comes your way. But let&#039;s assume it&#039;s being offered for sale on a website, and the seller hasn&#039;t provided any pictures or videos of the chain, etc. How can you detect it? If you look closely at the image of the reverse, specifically the leg of St. George, the horse, and the cloak, you&#039;ll find perfectly straight horizontal lines on the design, which disappear from the background. Let&#039;s analyze these lines:<\/p>\n\n\n\n<p class=\"has-text-align-right wp-block-paragraph\">Are these traces of cleaning? No, no matter how meticulous a person is, they could never clean a coin with lines of equal spacing and depth like this. Also, based on their shine, the lines look as if they were part of the die and were not &quot;added&quot; to the coin after minting. Cleaning, as is known, scratches the surface of the coin and changes its color or shine. So the piece was minted like this from the beginning!<\/p>\n\n\n\n<p class=\"has-text-align-right wp-block-paragraph\">\u2013 Very interesting! So perhaps these are the traces of grease lines that were applied with a brush to the surfaces of the coin dies? The answer is no for two reasons: First, those lines \u2013 by virtue of the brush strokes \u2013 could never appear this precise, as each bristle of the brush has a different length and thickness, and also carries a different amount of grease than its companions. Second, these lines, called die polish lines, and the best examples of them in Egyptian coins are the silver pieces minted during the reign of Sultan Hussein, appear only on the background of the design and not on the design itself\u2026 This in itself raises an important question: Why do the brush strokes appear only on the background? The reason is that the greatest amount of pressure occurs at the points of contact between the two dies at the moment of minting the coin, and this is usually between the raised design of the front and the raised design of the back. Thus, these grease lines are completely erased, while their traces on the background remain clearly visible to the naked eye.<\/p>\n\n\n\n<p class=\"has-text-align-right wp-block-paragraph\">So these aren&#039;t cleaning marks or grease marks, then what are they? If we knew that even laser beams have an extremely high degree of precision for drawing even the finest lines, the mystery would disappear, and we would realize that the counterfeit molds were manufactured with a laser, which left us these lines to expose the piece! The aim of this post is to reassure the reader that there are now counterfeit parts manufactured using laser technology, but rather to encourage them to have confidence in themselves as long as they are armed with knowledge \u2013 forgers are still failing to produce parts that resemble genuine ones in every way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Moheb Rizkalla<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"272743\" src=\"https:\/\/arabcollector.com\/wp-content\/uploads\/2020\/11\/88934595_1662253447266017_2797310018041413632_o-Small.jpg\" alt=\"\" class=\"wp-image-272743\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"272744\" src=\"https:\/\/arabcollector.com\/wp-content\/uploads\/2020\/11\/89018838_1662253437266018_8304158089578283008_o-Small.jpg\" alt=\"\" class=\"wp-image-272744\"><\/figure>\n<\/figure>","protected":false},"excerpt":{"rendered":"<p>There is still a fear, perhaps even terror, of the bogeyman called counterfeit currency that grips a large number of enthusiasts.
