At present, a transparent plastic bag is commonly used to store ancient coins, which has different specifications such as large, medium and small, and has many advantages such as easy storage, small size, convenient carrying and viewing. However, because this plastic bag is made of PVC, it has poor air permeability, and it is easy for moisture to enter in rainy days, which leads to the increase of moisture temperature in the bag and corrosion of ancient coins, which greatly reduces the appearance of ancient coins. In addition, this kind of plastic bag has a small import and export, which is easy to cause direct damage to some fragile coins. Therefore, if you plan to keep coins for a long time, you'd better not use them.
In addition, some people use foam plastic with pins or threads to save ancient money on cardboard, but it has many shortcomings such as large storage capacity, high cost and inconvenient carrying and storage. Moreover, the needle is made of iron, which is in contact with copper coins for a long time, and is prone to displacement reaction, rust water and pollution of ancient coins, so this method is rarely used at present.
Knife cloth coin
As far as surviving knives and cloth coins are concerned, they need to be stored separately, and there is no special storage device at present. A few collectors with deep pockets often ask people to make special storage devices, but the cost of opening a model is more than 1000 yuan, which is obviously too precious for small and medium-sized collectors. Ordinary people can choose some discarded cartons, such as knives and cloth coins, which can be put in longer ginseng cartons. It is best to add some absorbent cotton and sponge below to reduce friction. If you distribute coins, you can choose some checked cartons.
Precious paper money is usually stored in round plastic boxes. There are many models of this plastic round box, so it's best to choose the model that matches the size of ancient money. For thin, crisp and tender ancient money, cotton wool, paper and other things can also be used as cushions. Rare treasures that are particularly precious are even rarer. In the past, some people used boxes such as mahogany and ivory to set off their own preciousness. Of course, if we are unconditional now, we don't have to follow suit. In order to strengthen the protection measures, special measures such as vacuum packaging and nitrogen filling can be adopted to slow down the oxidation rate.
Iron money
Because iron money is easy to be oxidized and corroded, it is best to store it in a dry carton or a hard plastic box, with as much desiccant as possible around it. If conditions permit. You can go to the hardware store to buy some "metallographic antirust paper" and put it into small pieces. Each dollar is packaged separately to play a sealing role. For expensive iron coins, it is best to use vacuum packaging. On average, every three to five months, you can pick a dry and sunny day, take out iron coins one by one to ventilate and turn over.
Some ancient coins will be extremely seriously oxidized due to their own copper problems or long-term exposure to humid and acidic environment, which is called "bodiless" in numerology. Due to the serious oxidation, money is crisp and tender, like a piece of tofu. Therefore, the "unborn" money is generally not handled, so it must be handled carefully, and it must not be thrown away at will, otherwise the money will be destroyed. Some pre-Qin knives and cloth coins are relatively old, and the phenomenon of "bodiless" is more common.
Identification and collection methods of ancient coins To distinguish the authenticity of ancient coins, we must first master the characteristics and personality of coins in each era. Ancient coins have the characteristics of reflecting their times. Mastering their characteristics, we can easily know which era and what kind of ancient coins they are, and distinguish the authenticity according to their characteristics.
It is very important to scientifically distinguish whether the rust color on ancient coins is due to age or forged coloring, and to distinguish the authenticity of copper rust and copper color, because it is difficult to judge the authenticity of some counterfeit coins from the shape of words, but it is simple to put them firmly;
Familiar with the basic characteristics of counterfeit money, identify the minutes of counterfeit money, understand the basic characteristics of real money, and understand the basic characteristics of counterfeit money. The altered counterfeit money is uneven, the colors of the front and back of the spliced counterfeit money are different, and there are always flaws around the carved words. The pencil made by the sand turning method is slightly smaller and thinner than the real money. Knowing the basic characteristics of counterfeit money and observing it carefully, it is easy to find counterfeit money.
Master the relevant knowledge of ancient money identification, and understand the monetary theory, historical knowledge, common sense of ancient money casting and ancient philology knowledge, as well as laws and regulations of past dynasties;
Knowing the coins of the surrounding stock prices, many neighboring countries have passed through our country's coins and imitated our country's coins in order to master their characteristics and avoid being confused with our ancient coins.
The collection of ancient coins also depends on personal hobbies and collection value. The more the collection value goes back to the present, the more valuable it is, and the precious and rare metal coins with great significance are more valuable.
The ancient coin collection method packs ancient coins. Don't think that ancient coins are all copper coins, gold ingots and silver ingots. Since the Song Dynasty, ancient paper money began to appear and be used in circulation. From the earliest jiaozi to the later universal silver ticket, these kinds of ancient coins must be packaged in a single package. For currencies such as gold, silver and copper, the texture of these ancient coins is relatively soft, so it is inevitable that they will be damaged when they collide with each other. For currencies such as gold, silver and copper, the most easily scratched place is the embossed part, so in order to avoid similar situations, it is best to choose the packaging of the model matching the size of the ancient coins. For some relatively thin, small and tender ancient coins, you can use cotton wool, paper and the like as cushions. Of course, in order to strengthen the protection measures, special measures such as vacuum packaging and nitrogen filling can be taken to slow down the oxidation speed of ancient coins.
Prevent ancient coins from falling. Ancient coins made of precious metals will be bruised when they fall into the ground or touch hard objects. Even some ancient coins are completely rusted and will be smashed directly when they fall to the ground. In addition, playing with ancient coins too hard will also cause coins to break and break. These ancient coins are usually badly rusted and very fragile, and need special care and treatment.
Put it in a box. It is best to store ancient coins in dry paper boxes or hard plastic boxes, and put as much desiccant as possible around them. Of course, you can also go to the hardware store to buy some "metallographic anti-rust paper" and package it into small pieces. Each dollar is packaged separately to play a sealing role. For precious iron coins, it is recommended to use vacuum packaging, which is turned once every three to five months on average, because this way is the safest way to preserve ancient coins at present.
Don't destroy the old rust on the surface of coins. Some experienced coin collectors will find that the surface of ancient coins generally forms protective rust, also called old rust. Rust is hard, green, blue and red. These old rusts can protect coins to a certain extent, and it is best not to destroy them.
Handle with care. This requirement is especially aimed at bodiless coins. Generally, intangible money doesn't need any treatment, but it must be handled with care and never thrown away at will, otherwise the whole money will be broken at any time.
Ancient coins should belong to Tibet. The collection of coins should be kept according to the age and category. Because ancient coins with different textures have different requirements on temperature and humidity, they can be classified into drawers, or they can be stored in different coin books or plate-type coin boxes. Dry the coins before they enter Tibet to avoid being touched by sweaty hands. Coin cabinets, boxes and books should be kept in a dry and dark place to avoid rusting due to moisture. If it is paper money, it is necessary to prevent oil pollution and pay attention to mildew and moth prevention. In summer, especially after the rainy season in the south, you can take these paper money out to bask in the sun.
Toothpaste scrubbing. Of course, this method is suitable for coins made of gold, silver and copper in ancient times. They are metal coins. When stored for a long time, it tends to darken, which affects the ornamental value. In order to achieve the purpose of proper improvement, a small amount of toothpaste can be coated on the surface of these metal coins and then cleaned with water. You can also gently wipe the dirt that is not easy to remove in the cleaning process with a soft cloth prepared in advance, but try not to brush the dirt with a brush.
