Each coin has a history: about its period, its route, and its worth. It is your duty as its custodian to preserve that story to the generations. The Air-Tite Model I capsule is the choice of the professional to ensure that legacy is never tarnished, never besmirched, and absolutely secured.
Be it the experienced numismatist housing a historic treasure or the precious metals investor housing a pristine bullion coin, this capsule offers the ultimate assurance.
The Air-Tite Model I 41mm Black Ring capsule is not merely a plastic case it is a carefully designed preservation system. The 2 pieces and snap fit design forms an airtight enclosure that much minimizes exposure to the air moisture, and environmental pollutants that are the main causes of tarnish and corrosion. This protective cover is critical to keeping your collection in condition, thus its value, over the decades.
The unique characteristic of this holder is that it has black foam ring in it. This element is an all-purpose aspect that answers the fundamental requirements of discriminating collectors. Mechanically, it can serve as a safe gasket, having a flexible, adjustable fit that can be particularly important in coins with a small difference in diameter, such as older currency or some casino tokens. This eliminates the rattle and micro-abrasions that can be caused by an ill-fitting holder, something that is often an issue with collectors who have experienced coins being damaged through the movement in a capsule. Aesthetically, the deep black ring can make a beautiful framing effect, enhancing the coin design, and giving the details of the coin a professional sharpness.
This implies commitment to the future of the coin. One must learn all materials involved with that protection. Many collectors have experienced firsthand the dangers lurking in even the most commonly used plastics that, thus, want an archival safe holder, not because it is affording, but because it is mandatory.
A majority of cheap or older flexible holders are made to hold Polyvinyl Chloride. Even though this plastic becomes flexible, plastics are made very pliable because the manufacturers introduced chemical softeners known as plasticizers.
In time, particularly when heat and moisture conditions prevail, the plasticizers rise above the plastics and form greasy, green residues on the coin surface called "green slime".
This is not mere eye-sores; rather, they are responsible for initiating chemical action that translates into the formation of hydrochloric acid, which gets permanently etched into pitted surfaces on metals. Thus it becomes irreversible by any means, thereby reducing the numismatic value of coins significantly.
Air-Tite capsules are designed completely to avoid this risk. They come from injection molding virgin acrylic-a hard, chemically stable, and inert plastic-which contains no PVC, acids, or softeners that could degrade with time. It is also manufactured with a special non-yellowing agent so that the capsule remains clear in view of your coin for decades without a common feature of inferior plastics turning cloudy.
The black circle is not some common foam. It is manufactured using Volara, a brand of irradiation cross linked polyethylene foam. Museum and archival use of this material is because of a number of essential reasons. It is chemically inert, which implies that it will not react with the precious metals of your coin. It is also non-toxic, and not made with harmful blowing agents, thus it will not off-gas corrosive fumes into the sealed capsule environment over time. This guarantees the preservation of the fragile edge of the coin in the long-term since the foam holds it in a safe position without causing any chemical or physical harm.
