The meaning of commemorative coins

The "own job" of the coin is to act as a circulation intermediary. But with the need for collection and investment, some coins for other purposes were derived. Although there are different classification standards for coins. However, starting from the needs of the collection of coins, sorting coins according to the purpose of issuance should be the most essential and basic method. Precious metal commemorative coins, commonly known as gold and silver coins, are expensive and have a very small circulation. The country is currently focusing on the development of the international market in terms of politics, economy, and foreign exchange. It is widely spread across the country. The coins we produce are commemorative coins suitable for corporate brand promotion, new product promotion, souvenirs, and other industries. Our coin is a kind of ornament, a very commemorative gift for someone. Although coins are made of metal materials, they have a certain degree of hardness and seem to be hard to damage. In fact, it is not easy to keep coins. The quality of the coin is divided into 70 grades according to the American standard. The correct preservation method should slow down or stop the corrosion process of the coin, avoid damage, and try to maintain the original quality grade.

The use of commemorative coins

Coins are often used as commemorative coins in industries such as corporate brand promotion, new product promotion, tourist attractions, souvenirs, school celebration souvenirs, and advertisements. Coins are very meaningful gifts as commemorative gifts for some large-scale events or conferences. Coins have the advantages of easy use, wear resistance, and long circulation life.

Characteristics of coins

The chemical stability of the material of the coin, the material used for packaging and contact with the coin, the atmospheric conditions for storing the coin, and the contact observation of the coin. Generally speaking, gold is more corrosion-resistant than silver; silver is more corrosion-resistant than copper; metals such as zinc, aluminum, and iron are more susceptible to corrosion. For alloys, sometimes it depends on metals with more active chemical properties. For example, pure gold has a better stability. When copper is added to gold to form an alloy, coins are prone to black spots. But brass (copper-zinc alloy) is more resistant to corrosion in the atmosphere than pure copper. Polyvinyl chloride in the packaging material is harmful to coins. Polyvinyl chloride will gradually precipitate plasticizers to corrode the coins at room temperature, which can cause irreversible losses. Sufficient attention should be paid to this point, especially to copper and copper alloy coins.
