Original title: 8001 Gold Net Blue One 1 Jiao Note is 8000 yuan. The vast number of collectors know that there are many editions of 8001, such as Golden Armor, Dioptric Corner, Overlord Cloud, Color-changing Fluorescent Filament and so on. These banknotes are all experimental banknotes made by the mint in order to upgrade the anti-counterfeiting technology. On November 20, 2012, in order to test whether a new type of ink has the phenomenon of ink penetration on the fifth edition of banknote printing paper, Xi'an Banknote Printing Factory of China conducted an experiment. During the experiment, the whole process was kept secret,garment measuring tape, and 50000 sheets were printed in one batch, with the numbers of N1D2400001-N1D2440001. After all the preparations were completed, 20000 banknotes were put on the market in 2013,personalized tape measure, and the number segments were N1D2400001 ~ N1D2410000 and N1d24200001 ~ N1d2430000, and the banknotes were quickly recovered to observe the changes in circulation. This experiment was declared a failure, because the new ink did not match the fifth edition of paper, the fifth edition of paper was thicker than the fourth edition, if the printing ink could not be eaten at one time, so many printing experiments were carried out. Through social recycling, it was found that this printing technology would appear ink penetration phenomenon after circulation, printed tape measure ,personalised tailor tape, and after many times of printing, the ink color became heavier and color difference, so the experiment was stopped. Expand the full text In 2015, China issued a new edition of the fifth set of RMB. Xi'an Banknote Printing Factory looked back for half a year to sum up its experience. The experimenter accidentally found that a line of the lowercase 1 below the banknote had a discoloration effect, which could be seen by the naked eye without any instrument. It was blue in the distance and brown in the near future. So the working group sealed the banknotes and reported to the higher authorities. It is this time to look back and sum up the experience, inadvertently found that the effect of ink dimming has pushed forward the technology of ink dimming in our country for 20 years. Ink dimming technology has been blocked by foreign countries and controlled by our country. This discovery has given our banknote printing experts a new way of thinking and a backward experiment on the situation at that time. After 155 days of hard work, we finally overcame difficulties and achieved significant results, and the relevant personnel were also commended. This technology was soon tested in the zodiac commemorative banknotes printed by our country for the Macao Special Administrative Region, so that our country was at the same starting line as developed countries in the technology of color-changing ink. After the delisting of the fourth edition of the coin in 2018, many mints are clearing their stocks and distributing them to commercial banks. 8001 Golden Net Blue One formally meets with the collectors. However, some collectors find that there is no original bundle of film in the market. Relevant people infer that the bundle needs to be cut off when the experimental coin of the banknote printing factory is out of the warehouse. If it is not cut off, it is illegal. Because these collections are not in circulation in the market, it is hard to find a banknote. Some people offer a sky-high price of 8000 yuan, and the price of a seal is around 100000 yuan.
