2. The voucher number cannot identify the true or false RMB< The way to identify counterfeit banknotes is as follows:
look at it:
1. Watermark:
white watermark: under the two-color irregular horizontal number on the front of the fifth set of RMB 100 and 50 banknotes, you can see the words "100" and "50" with strong light transmission< Holographic magnetic windowing safety line:
there is a holographic magnetic windowing safety line on the right side of the middle of the back of the 100 yuan and 50 yuan banknotes. The holographic patterns of "RMB 100" and "RMB 50" can be seen from the perspective of light. The real money is torn a little, and the wire is independent. The wire of the fake money is usually printed on the paper money
3. Light variable ink:
the denomination numbers on the lower left side of the front of the fifth set of RMB 100 and RMB 50 coupons are printed with light variable ink. When the vertical view of the ticket is tilted to a certain angle, the face value of the 100 yuan ticket will change from green to blue; The denomination of the $50 coupon will change from gold to green
4. Offset printing pattern:
the fifth set of RMB 100 yuan and RMB 50 yuan coupons, with the center on the left side of the main scene pattern, facing the light, the two patterns are accurately connected to form a complete ancient coin pattern

second touch:
1. Whether there is concave convex feeling when touching the portrait, Braille dots, the bank name of the people's Bank of China, etc
hand carved head:
the main front scenes of each coupon of the fifth set of RMB banknotes are Mao Zedong's head, which adopts hand carved gravure printing process, which is vivid, vivid, concave convex and easy to identify
2. Check whether the note is of moderate thickness and good straightness
gravure touch line: on the right side of the front main scene pattern, there is a group of lines arranged regularly from top to bottom, which are printed by the engraving gravure printing process, with a strong concave convex feeling when touching with fingers<

3
three listening:
that is, by shaking the banknote to make it sound, we can distinguish the authenticity of RMB according to the sound. The paper of RMB has the characteristics of straightness, folding resistance and not easy to tear. If you shake the banknote, flick your fingers or pull your hands symmetrically, you can hear a clear and loud voice

3. Too many, almost two of them.

5. First of all, we need the network culture business license, then the ICP, and the application of virtual currency transaction, and so on

6. QQ coin is a kind of virtual currency issued by Tencent in order to facilitate users to purchase the virtual goods and services it provides. Its official price is: 1q coin = 1 yuan. However, if the amount of recharge is large, there will be a certain amount of discount on some recharge platforms
it should be noted that this is the recharge price. If it's selling q-coin, because q-coin recycling is now done by some third-party platforms, there will be a certain cost. Therefore, the recovery price of Q coin is generally lower than the recharge price, remember!

7. First of all, gold does not always depreciate. In the short term, the price of gold is likely to fall. It should be said that in the long run, the price of gold will not fall. In the long run, gold will keep its value
then, the long-term value preservation of gold is determined by three factors: scarcity, rability and standardization
first, scarcity. The main gold procing countries are China, Australia, the United States, Russia, etc. Because the world reserve of gold is very low, it can be used as a general equivalent to a relatively high value commodity. If it's copper or lead, it won't work. There are too many reserves of these two metals. A counterexample: diamonds. The scarcity of gold is natural, while the scarcity of diamonds is man-made. De Beers, the world's largest diamond dealer, monopolizes the global diamond mines. The supply to the market is only one tenth of the proction capacity. In this way, the value of diamonds can be improved. If the diamond is purchased, the price of diamond recovered by diamond dealers is very low. Someone has done an experiment, spending money to buy a bare diamond, and then immediately went to a nearby diamond shop to try to sell it. The highest price of a diamond shop is only one third of the purchase price
the second point is rability. As a long-term value preserving commodity, it can't be oxidized and corroded after several decades, which is equivalent to devaluation. Gold Au, an inert element, hardly proces any chemical reaction in daily life. So hundreds of years later, a gold bar is still a gold bar, and it will hardly be oxidized. As a counter example, pearls, which are also very rare and valuable, have disappeared after hundreds of years. This is also the reason why it is almost impossible to excavate hundreds and thousands of years of pearls in archaeological excavation
thirdly, standardization. As long as the gold content (purity) is determined, the value of gold is determined, and it is easy to be valued and traded. Other gems and even diamonds need to be valued by professional appraisers. For example, the 4C of diamond valuation (carat # 8194; Weight, clarity, color and cut are very complicated and subjective
gold investment, e to its characteristics, is destined to be a long-term hedge, but not too profitable investment method. Many investors will use gold as a way of hedging investment, and other high-risk and high return investment portfolio, to achieve the purpose of "advance can attack, retreat can defend".

8. Agricultural procts uplink mainly refers to the use of Internet technology (such as Huinong network) to sell agricultural procts from rural proction to all parts of the country, especially the city (town) market, also known as "agricultural procts into the city", which is an effective way to promote the coordinated development of urban and rural areas and truly realize the common prosperity of the whole people
some preparations should be made for the development of agricultural procts:

1. Investigate what the local characteristic procts are and whether they are the bulk commodities generally accepted nationwide. In this way, the audience will be wide and the competition will be fierce. In this way, you must know what you want to buy for your procts
2. We must be prepared
there are more than 9 million sellers in Taobao tmall alone, plus other mall platform sellers, the number of online sellers in China is more than 10 million, which does not include new online sellers such as micro stores and micro businesses. The upward competition of agricultural procts must be quite fierce. In order to do well, we must be prepared for long-term operation, continuous learning and facing pressure
3. Reasonable positioning
whether agricultural procts are put on the market in the form of agricultural procts or prepackaged food must be reasonably positioned according to their own actual situation. Agricultural procts are often small in investment, quick in effect, low in single proct profit, and difficult to form brand benefit, but they are faced with low risk and relatively small pressure; Prepackaged food has large initial investment, high single proct profit, and is itself a brand proct. Sales is to expand brand market share. It can enter supermarkets and participate in agricultural proct fairs all over the country. In the early stage, there is no fixed sales channel, and there is great capital pressure before
4. Adopting cooperative operation to disperse business risks
in the early stage, new instries are bound to be very difficult. No matter how good the successful cases are, they are all on paper. Only real practice and down-to-earth actions are the dawn of success. To operate together with some like-minded people can make up for the lack of liquidity and investment in the early stage, and obtain free capital and manpower, Second, we can pool our wisdom and make concerted efforts.
5. We must keep learning and keep up with the pace of the market and trading network platform.
now the market is changing all the time, and the major online shopping platforms are constantly optimizing their own systems. Only by constantly adapting to the rules of the platform, can sellers get the push of the platform and the opportunity of free display
6. Do a good job in investment budget and investment plan
no matter how big or small a business is, it should have its own independent investment budget, budget how much investment it needs to make a profit, and give yourself a bottom line. Investment plan is the basis to judge whether an enterprise's operation at each stage reaches the expected goal, so as to adjust the investment appropriately
7. Guarantee of proct quality and after-sales service
procts are the foundation for enterprises to survive. Agricultural procts often have no unified standards, and the quality is uneven. Long term operation must focus on quality, not only to ensure good procts, health and safety, but also to ensure the same quality. At the same time, after-sales service should be done well to win repeat customers< In the early stage, when there is no stable sales channel or online traffic transaction, it is the first priority to expand the sideline and maintain survival. We can carry out agent buying business, such as Taobao service station, etc.
9. Do a good job in marketing plan, such as low price sales, small profit and quick turnover, High price sales, gifts, etc

in addition, 9050ar crown (commonly known as "king of blue crown") is different from others (AR crown and numbers are light blue (partial sky blue), others are dark blue (partial blue black)), and the price is twice or more higher

extended data

the collection of the complete number of paper money rose relatively late. At present, few collectors can have the complete number of three editions of paper money in China. This is a great and arous project, and they can't achieve a little without ten years' efforts

the common edition collection is a popular collection theme which has been popular for many years. Basically, it can be realized as long as there are funds. The crown collection not only costs money but also energy. A complete set of crown collection is a symbol of collection strength.

crown collection tests a collector's perseverance. There are many unknown factors in crown collection. If you want to join the ranks of crown collection, you should be prepared to sacrifice three precious things: time, money and energy
