Silver coins are coins made of silver, which have a general collector's value and are represented by "Yuan Datou". It refers to silver and other properties. For example: Ming Gaoqi "heavenly world to play the moon poem preface": "the history of the Yuan" into the Chinese book table into the imperial edict to give the compilation and repair of the sixteen silver coins

Xu Ke "qing taolu class notes - stick cheat - fake master's name for the book to cheat": "crone back, then said the master in the tea house for turning the party forced, non-silver twenty rounds shall not come off." 周立波 《暴风骤雨》 第一部十六："他说著，从衣兜里掏出一块 袁頭银币给 xiao captain and zhao yulin 看。". From the point of view of coin collection, it is not recommended to clean off the black oxidized layer on the surface of silver coins (also known as the "coating"). Doing so will easily damage the surface of the coin and affect the collection value of the silver coin. Silver coins with a good coating are often sought after by collectors, and can even fetch several times the price of a brand new uncirculated version. Silver coins In addition, the method of wiping with a toothbrush dipped in toothpaste can indeed clean up the oxidized layer of silver coins, but be sure to use soft bristles, otherwise the silver coins will definitely be damaged. The method is difficult to get just right and is not recommended. Alternatively, it can be cleaned with a low concentration of acidic liquid. This method also carries the same risk of damaging the silver coin. You need to be very familiar with chemical acids to do this. Chemical Reaction: The same silver coins with identical preservation conditions will produce different results, with some having vulcanized cladding and others not. This is related to the production process of silver coins. The cladding of silver coins always originates at the rim and gradually works its way inward (not all, but most). Including the new Chinese silver coins (with or without plastic box) and the old silver dollars (without box), the oxidation of many of them starts from the edge of the circumference, and less from the center of the silver coins. Why? New Chinese silver coins wrapped, often see one side of the coin oxidized obviously, the other side of the more slight or no oxidation. There may be a relationship between the placement of the coin and the sparseness of the gap between the coin and the box. Obverse of Chiang Kai-shek Head Silver Coin For the new Chinese silver coins, the 999 silver ones are easy to be oxidized by sulfidation, and the coins that are not 999 pure silver are relatively much less (usually with only light yellowish-brown oxidation or chlorinated white haze); for the old silver dollars, even though all of them are not 999 silver, there are quite a lot of colorful sulfide as well. Why is this? Silver coin oxidation and chlorination, previously said to be light, microorganisms and other reasons, the Mint scientific research shows that the main chemical reasons, followed by physical form constraints and minting process. The effect of ultraviolet light on corrosive compounds on silver surfaces needs further study. What is the result of oxidation if a spherical sterling silver body is placed in a suspension line overhanging a sealed box to avoid air pressure, water vapor stratification, light, etc.? From which parts does the oxidation begin first? (When I was in middle school, I wondered: where are the positive and negative poles of a magnet that is perfectly regular and spherical?) There have been collectors complaining that NGC coins will still oxidize after being boxed in a box, in fact, before being boxed in a box, the grader is *** silver coins to observe, the *** environment at the time and the coin's unveiled state before leaving the mint are also very relevant, and not necessarily a grading box issue. Some of the surfaces of the mint's dies are meant to be oiled, and some of the coins and medallions are oiled in the die casting; some of the coins and medallions are meant to be antioxidant treated with a film after they are pressed. Oil, chemical film, has been kept untouched, then, more or less will affect the surface effect of the product after N years. Early large size silver coins, the original seal sealed, no round plastic box inside, directly sealed, the chemical composition in the plastic seal and the factory oil film, etc., will affect the surface of the coins, e.g., 1986 5 ounce Dr. Sun Yat-sen silver coins. Chiang Kai-shek Head Silver Coin Reverse Whether it is the old silver dollars or the new Chinese silver coins, the tarnish is not all "bad", according to the different results of the tarnish, some of them are very popular, and their value is higher than that of the coins that have not been tarnished, e.g., the silver coins that have a beautiful sulfurized color. Foreign countries also pay more attention to this kind of coins, many collectors regarded as rare treasures. Some of the early New China silver coins, occasionally see small black spots, especially non-999 pure silver small specification silver coins, is suspected to be the minting process of coins stuck on the surface of the iron element impurities caused. Authenticity appraisal in the last two years appreciation is amazing "Yuan Daitou" is the silver dollar collection of the most common one, but also in the hands of the public collection of the most one. 1914, Yuan Shikai in order to solve the military expenses and improve the political status of the individual and the issuance of silver dollar currency, because of the silver dollar casting his side of the body image, so also known as "Yuan Daitou". Yuan Datou". "The Yuan Datou was first minted by the Tianjin Mint, followed by mints in Nanjing, Guangdong, Wuchang, Gansu and other places, and then it became the common currency at that time. Due to the large number of minting places and the large amount of minting, many versions appeared. Although there are differences in the version, but the standard weight of "Yuan Datou" are seven money and two cents, to today's measurement is 26.697 grams, the color is 89%; there are one yuan, in the yuan (50 cents), 20 cents, 10 cents four kinds of denomination; according to the number of the year, "Yuan Datou" There are mainly 3 years, 8 years, 9 years, 10 years version. silver coins version of different price different "Yuan Daitou" in the various versions of the price also varies. 3 years version of the most common, 10 years version of the second, the market price of a dollar coins in the $420 or so; 9 years of fine hair version of the better workmanship, the market price of $500 in the Yuan; 8 years version of the relatively few, the market price in the 700 yuan or so. In the other version of the one dollar "yuan datou", plus cast "Gansu" two words version is also precious. The edition of "yuan datou" by Gansu mint along the 1914 edition, in the Yuan like around the casting of "Gansu" two words, and only minted tens of thousands of pieces, the scarcity of survival. The most precious and rare is the 1914 signature version of one dollar, which is engraved on the right side of the image of Yuan Shikai with the Latin signature "L-GioRGi" of the Italian engraving expert "Rorge George", which is equivalent to the meaning of the "sample coins. ", by the tianjin mint trial minting, the number may be in one or two dozen to hundreds, did not circulate, the amount of survival is very small, the general collector is difficult to witness its "lushan true face", in the coin auction is also rare to see. The market price has been in the hundreds of thousands - hundreds of thousands of about, is the modern silver coins in rare treasures, for domestic and foreign coin collectors concerned. Recognize the authenticity before investing There are many fake 'Yuan Datou' on the market. Pseudo "Yuan Datou" is generally less than heavy, if heavy is increased or thickened, color gray sound sharp; there are also heavy and the size of the same as the real one, the inside is an alloy, the outside is wrapped in a layer of silver. This way of forgery is a lot of fake antiques **** the same practice. It is understood that the identification of silver dollars to its historical characteristics, manufacturing process, ornamentation, etc. have in-depth knowledge, can not just look at the surface phenomenon. According to Mr. Yang, his store alone, since the opening of the Temple, has received more than 40 "Yuan Daitou", at the same time, there are more people waiting to buy. The ratio of selling citizens to buying citizens is about 1 to 10. Mr. Yang said, compared, we can find that "Yuan Daitou" significant appreciation and the rise in the price of silver is positively correlated with the world's silver reserves and stocks are decreasing year by year, the price of silver coins is likely to continue to rise. Of course, the current price is not low, the public should be cautious before entering the market. Silver Coins Tips Chemical Identification Methods for Silver Coins,Silver coins will be rubbed several times on a litmus test stone until there are silvery-white scratches, and then a drop of nitric acid will be placed on the scratches. At this point, if it is a genuine coin, the mixed liquid on the scratches is earthy yellow, while the counterfeit coin is colorless and transparent. If the silver coin does not contain enough silver, the mixed liquid of nitric acid also appears as a different excess color of earthy yellow, but not strong enough. The lower the silver content, the less intense it is. The precipitate crystals of pure silver nitrate are white and transparent, because the silver coins contain impure silver, accompanied by a small amount of other non-ferrous metals, so that the nitric acid compound precipitate of silver coins is earthy yellow. The chemical precipitates of tin nitrate and lead nitrate are grayish-white substances. Preservation of silver coins Try not to touch the surface directly with your hands, because sweat stains on your hands will pollute the surface of silver coins, and it is best to seal the coins with sealed plastic, so that it is more convenient to view them, and it also plays a role in preventing the dust in the air from contaminating the surface of silver coins. Try not to collide with each other, because it is easy to leave traces. Silver coins If the silver coins are dirty, put them in warm soapy water and wash them slightly, then rinse them with water and dry them gently with a soft cloth, and finally place them in a dry and ventilated place; try not to rinse them with alkaline water, or brush them with a brush. Alkaline will easily cause corrosion to the surface of silver coins. Put the color-changing silica gel in the place where the silver coins are stored, which mainly plays the role of absorbing moisture; when dry, the silica gel is blue, and it will change to red after absorbing moisture. It's best to keep them in a safe that is protected from corrosion and moisture. Silver Coin Investing Intrinsic Value For thousands of years, silver has retained its value and utility as a currency and a means of exchange, despite the changing of dynasties. Silver has retained its intrinsic value and has never lost it. Instead, decade after decade, century after century, silver has always appreciated. The purchasing power of an ounce of silver today is about the same as it was 1,000 years ago, and there is not much risk involved. Physical Investments Silver coins and bars are a good choice for investment because you can hold him in your hands. Unlike stocks, which are controlled by a board of directors. You can decide how to use silver. They are also different from futures and other complex silver derivatives in that you can be sure that the silver you own is actual silver and not paper certificates printed by a bank. Yields Silver is much more volatile, and it offers higher yields than gold and other precious metals, which stems from silver's rarity. The amount of silver traded in the world is very small and any small purchase can have a large impact on the silver market. Historical data shows that the price of silver rises very quickly, and can rise by 10 to 20 percent in a few weeks. Uses You can't use stock for antibacterial drugs, you can't use your bank balance to make a movie, and you can't use any other metal for conductive wiring. Silver is a stark contrast; it has thousands of industrial uses, thus limiting the amount in circulation and appreciating the value of the silver in your hands. When you buy TVs, computers and other electronics, you own silver. Silver is also found in your batteries, in car bearings and in medical devices you are least likely to buy. Silver is also found in the solar energy industry and the water purification industry. As the world and technology continue to evolve, the demand for silver will only increase. Functionality Gold and silver are regaining their monetary utility and finding a foothold in global circulation. Various *** and their central banks are looking for new investments to support their speculative investments and add value to foreign currency. China and India have purchased large quantities of gold to diversify their foreign exchange reserves, with India's one-time purchase of 200 tons in 2009 being the largest in its history. People all over the world are beginning to realize that the value of the metal is not just for investment, but is also an actual tangible asset. As more people invest in silver, the price is bound to rise, thus benefiting silver coin investors.
