Silver Coin Preservation Guidelines:

1. Avoid contact with sweat and oil from your hands: Sweat and oil from your hands can damage the surface of the silver coin, causing it to oxidize or leave fingerprints. When handling silver coins, it is recommended to wear cotton or latex gloves, or use tongs to handle them, to prevent direct contact with the coin surface.

2. Store in a dry environment: Silver coins are very sensitive to moisture. A humid environment can easily cause silver coins to oxidize and turn black, and even develop spots or rust. When storing silver coins, they should be placed in a dry environment. Dehumidifiers can be used to reduce the moisture in the air.

3. Avoid direct sunlight: Prolonged exposure to sunlight will darken the color of silver coins and damage their luster. When storing silver coins, they should be placed in a dark place, such as a professional silver coin storage box or a sealed bag.

4. Use professional storage tools: Storing silver coins in specially designed coin boxes, protective cases, or plastic sleeves can effectively prevent them from coming into contact with the outside world and prevent scratches or oxidation.

5. Avoid contact with other metals: Silver coins should not be stored with other metal coins to prevent scratches or other damage caused by friction.

6. Regular inspection and maintenance: Avoid frequent cleaning of silver coins to prevent damage to their natural patina. If oxidation occurs on the surface of the silver coin, it can be cleaned with a professional silver coin cleaner, but avoid using strong acid or alkaline cleaners.

Proper protection and storage can effectively maintain the condition and value of silver coins, which is crucial for the long-term collection of precious silver coins.
