Not suitable for playing military coins

It is generally not suitable to directly play with bare coins, especially refined coins, uncirculated coins, or high-end coins. The place where the hand touched the military coinmust be the place that corroded and turned black first. If you want to hold the coin, use a clean soft paper or cloth to separate the edge of the coin in your hand.

Cleaning military coins

For old traces, if necessary, use the advanced drawing eraser without grit to moderately wipe the test. For coins with large dirt and particularly dirty, ultrasonic cleaners can be used to clean them when possible, and alcohol should be used as the cleaning liquid at this time. Coins should be suspended in the cleaning liquid in a net bag to prevent the coins from directly contacting the inner wall of the washing machine and causing damage because the mechanical vibration of the inner wall will damage the coins when they collide with the coin. In this way, dirt can be removed without scratching the coin. It should be noted that washing cannot improve the grade of the coin but is only useful for viewing (removing the excess material adhering to the coin). The quality of the coin depends only on the degree of wear of the coin itself.

It is not recommended for coin collection to dispose of the appearance of the coin by yourself. No matter what chemical agent is used, it will not restore the original appearance and will leave varying degrees of damage.

It is recommended to protect the original site by sealing and sealing with alcohol disinfection on the original basis. This method is also adopted in the protection of cultural relics.

Store it in a coin collection bag or a stamp collection bag and store it together with a moisture-proof agent (some food in bags).

It is strictly forbidden to touch with bare hands, touch with water, damp, strong acid, and alkaline substances.
