The correct way to preserve commemorative medals

Commemorative medals are a general term for commemorative medal-shaped items, including commemorative medals, collectible commemorative medals, and decorative commemorative medals.
The unit price of custom commemorative medals ranges from a few yuan to several hundred yuan, and is generally priced according to customer requirements. Customized commemorative medals are divided into two categories: one is a precious metal commemorative medal made of pure gold and silver, and the second is made of copper or alloy after electroplating. The appearance of the two is similar, but the value of the two is very different. Gold and silver commemorative medals have appreciation potential and collection commemorative value, while copper or alloy commemorative medals only have certain collection commemorative significance.
Since commemorative medals need to be preserved for a long time, the preservation of commemorative medals is very important. Today, the editor will explain the correct way to preserve commemorative medals:
1. Avoid moisture
Most commemorative medals are made of metal materials, which are easy to rust after being damp. Therefore, when collecting, they should be placed in a dry place and away from a humid environment. For commemorative medals stored in sealed boxes, it is best not to open the box for storage unless absolutely necessary to avoid moisture and rust.
2. Avoid hand prints
It is best not to touch the commemorative medal directly with your hands, especially with wet or sweaty hands. Because touching the commemorative medal directly with your hands, it is easy to leave fingerprints or sweat marks. When appreciating and playing with it, you can wear thinner gloves or use softer plastic tweezers to pick it up and put it down along the edge.
3. Avoid acid and alkali
Acid and alkali have a strong corrosive effect on metals, and the same is true for metal coins. Light ones will cause the commemorative medal to discolor and oxidize. Therefore, commemorative medals cannot be placed together with acids and alkalis; even if you have to use acids and alkalis to remove rust, you should clean it in time after use.
4. Avoid bumps
When taking and putting commemorative medals, avoid friction and bumps with each other, especially gold and silver coins, which are heavy and soft and easily damaged. Avoid damaging the appearance of the commemorative medals. Even if there are small bumps, do not use blunt instruments to handle them at will, and do not use toothpaste or other ointments to scrub them. It is better to let nature take its course.
5. Avoid fire. Although metal medallions will not be destroyed in fire, they will be deformed if exposed to fire, and their color and quality will be damaged if exposed to fire. Their collection value will inevitably be greatly reduced. If conditions permit, it is best to store them in a metal cabinet or safe.
