Coin Products
The Problem:
The first problem is that metals corrode by reaction with common gases in the atmosphere. These corrosive gases react with both Ferrous (iron based) and Non-Ferrous metals, however these gases are the primary cause for corrosion to Non-Ferrous metals such as; Gold, Silver, Tin, Copper, Brass, etc.
The second problem is that your coin holder is not airtight. I am sure you have experienced toning on silver coins after they have been graded.
This is a list of common corrosive gases that can damage your coins and examples of how they are produced:
- Hydrogen Sulfide (HS2) produced as affluent from pulp mills, oil refineries, heavy industry and decaying vegetation
- Carbonyl Sulfide (COS) produced from fossil fuel combustion (such as burning coal, gasoline, oil, etc.) wood fires and ocean surfaces
- Sulfur Dioxide (SO2) produced from fossil fuel combustion and smelting operations
- Hydrogen Chloride (HCI) produced from fossil fuel combustion and ocean surfaces
And here are the results of a test performed by Dupont comparing ordinary plastic vs. Intercept Technology™
In other words, your coin holder won't protect your coins from corrosion nor will placing your holder in an ordinary plastic bag !!!
The Solution:
Coin Armour products utilize Intercept Technology™ in the production of storage bags and other storage products for the long-term preservation from the harmful effects of corrosion.
Intercept Technolgy ™ effectively neutralizes corrosive gases and literally halts Corrosion in its track:
Intercept Technology™ provides effective tarnish protection for non ferrous metals such as silver, gold, brass, copper and bronze.
- The inert material will not out gas (release corrosive gases) like charcoal based products.
- Is non toxic, non abrasive and temperature independent
- Protects items from tarnish for up to 10 years per mil of material thickness.
- Does not leave deposits on items it protects.
- Does not contain volatile corrosion inhibitors (VCI).
- Cleans trapped air of harmful gases making a micro-environment free of corrosive gases
Please feel free to visit our store. We currently only have a limited number of products available, but we plan to add more in the near future. Before you do visit our store, check out some examples below from test studies performed by Lucent Technologies utilizing Intercept Technology™ vs. no protection:
