Effectively and safely storing any good quality currency collection is a task that can never been taken lightly. It is critical that only using a type of currency sleeve that is specifically designed to ensure the safety of that currency for extended periods of time. The materials used in fabricating these currency sleeves must be safe enough to be in prolonged contact with the currency. Inexpensive currency sleeves are prone to yellowing and cracking as they age, and are made from chemicals and contaminants that can seriously damage the paper over time. It is essential to only use products that are made for long-term archival storage of paper currency.
The lesser quality plastics contain a chemical compound known as PVC, or polyvinyl chloride, which deteriorates over time and emits acids and gases which will transfer into the paper, causing the notes to appear as if soaked in oil, or so brittle as to shred at the slightest touch. The best way to guarantee that the currency storage method is safe is to use products recommended by currency, stamp or coin dealers.

In other words, it is known as ‘archival-safe’. Common household products such as plastic wrap, plastic bags, or windowed envelopes should never be used for storing paper currency. Notes should be also stored or displayed out of direct sunlight to prevent fading.
