Oxidation of Coins
Did you know? Oxidation
is the major reason for the degradation of most coins and any item containing metallic parts. What is
Oxidation? It is the combining of Oxygen in the air with the metals in
your coin/collectible, more commonly known as rust, tarnish, and corrosion. So to
prevent oxidation, we simply need to ensure that there is minimum
exposure of the metal(s) in your coin/collectible to the environment (air) and any type of catalyst like moisture (water). Always ensure your coins/collectibles are kept clean and dry and stored in a dry place.
For coins, we can prevent further oxidation in many ways, but the three most practical ways are to:
1. Seal each
coin in a separate holder.
2. Store multiple coins in a closed container with
3. Store the coins in an almost airless and
airtight (vacuum) container.
