Military coins are also called challenge coins. Challenge coins are commonly used in many fields. In the hands of some domestic military fans who love military collections, there are also many physical collections of challenge coins. So how to save military coins? The following is a detailed introduction.
The packaging method should be chosen
Isolate the air
Military coins do not have to be cleaned
To preserve the coins, you should first choose the packaging method, which is not only convenient for viewing but also conducive to protecting the coins, which depends on your conditions. The optional packaging includes non-PVC plastic boxes, paper clips with polyester film holes, polyester film bags, paper bags, etc. Optional materials are polyethylene, polypropylene, polyester film. To facilitate appreciation, it can also be placed in the coin collection book based on transparent packaging. The key point is that you cannot use polyvinyl chloride-containing materials to pack and store coins. Its harm must not be underestimated.
Paper clip storage is to punch out coin holes of different diameters on the cardboard, lined with transparent film, and then use a stapler to nail it or glue it with a sticker. Use paper clips for storage, which is convenient for writing and viewing. This method is suitable for all kinds of coins. If the lining transparent film material is polyvinyl chloride (PVC), long-term storage is likely to cause corrosion or damage to the coin metal. But now there are higher-end paper clips.
The coin box storage is that the coin box is made of transparent hard plastic, with a square or round shape, and is lined with soft cushions. The coin box can have various sizes. The price of the coin box is slightly higher, and it is transparent and intuitive, not easy to damage the coin, but it is not easy to write instructions. Can be used to collect coins, especially refined coins, and gold and silver coins. Encapsulated coin box, completely airtight, can be affixed with logos and bar codes.
The simplest way to isolate the air is to soak the coin in absolute alcohol. The disadvantage of this method is that it is not easy to watch, but the effect is better. Coins should be stored in a ventilated, clean and dry place.
Coins generally do not need to be cleaned, especially not with ordinary rubber or commercially available glass fiber wiping sticks, which will scratch the surface of the coin. If there is green mucus produced after packaging harmful materials on the surface of the coin, it can be cleaned with absolute alcohol. The stains and fingerprints on the coins can also be cleaned with alcohol, which is effective for new stains and can prevent further erosion of the coins by the stains and fingerprints.
