I would like to introduce as well as share how to preserve banknotes that I used to do, it is very well preserved even though you can hold them, touch it, and in a humid environment.
1. Two-layer rule:
The two-layer rule is that you protect your banknotes through two layers of protection. This layer of protection is Semi Protector and Banknote Protector Sheet. A Semi protector helps you to hold the bill to avoid contact with your hands, the environment that affects the banknote, especially dust. As for the Banknote protector Sheet, it is an armor that helps you to cover dust as well as external damage that affects the bill, otherwise, it helps you to display your collection neatly and safely without folding or stain…
2. What is The Semi Protector?
The Semi Protector is the first layer of protection, this is a polymer material (plastic) but it is a NON ACID plastic, which means there is no acid that makes the paper yellow over time. Searching to buy this wrap is very easy, directly ask the seller for money, of course, they will have it for you to buy, usually, this type of wrap is more expensive than normal or food packaging, so it should not be used for everyday food packaging. Wrap the banknote because the acid in the plastic will oxidize over time, causing yellowing of the banknotes
Remember, go to a reputable seller because it is difficult for you to know whether it is Free Acid or NON Acid so you will easily be deceived by the seller to sell you and the consequences will be unimaginable.
3. The Banknote Protector Sheet:
It is the place to display your collection, The Banknote Protector Sheet will be the place for you to store the bills according to the pre-stamped pattern, the most common is to dry 3 compartments but still have 4 compartments, 2 compartments, and 1 compartment. And remember, like protecting money, drying is the place to protect the second layer of your bill, so drying is also made of acid-free plastic.
“Find to buy it from the reputable and reliable, don’t waste your money so that your money will be damaged, causing unfortunate losses.”
The Banknote Protector Sheet has many production countries, such as Germany, Thailand, China, or the US. It doesn’t matter which country produces it because basically, they produce all good materials, no acid, the difference is the shape, thickness, and hardness of the drying only. The example below is the exposure I trust to use because Made In the USA, the drawback is that the sheet is a bit flexible and soft.
