Protecting a collection is not merely a matter of storage; it is an act of preservation. Each coin, whether a historic silver dime, a rare three-cent nickel, or a modern gold bullion piece, represents a tangible link to history and a significant investment. Exposing these assets to atmospheric contaminants, corrosive skin oils, or improper storage materials can lead to irreversible damage, permanently diminishing their beauty and value.
The Air-Tite Model A Ring-Type Capsule is the definitive solution for collectors who refuse to compromise on protection. Engineered with archival-grade materials and manufactured to exacting specifications in the United States, this capsule provides a secure, inert, and visually stunning environment for your most cherished 18mm coins. It moves beyond simple storage, offering museum-quality preservation that ensures your collection remains in pristine condition for generations to come.
In the world of numismatics, not all protection is created equal. While many retailers offer coin holders, a closer examination reveals a significant gap between basic storage and true archival preservation. The market is saturated with products that make claims of being "safe" or "PVC-free" but fail to provide the scientific basis for these assertions, leaving collectors vulnerable to the very long-term risks they seek to avoid. The most critical distinction lies in the science of the materials used.
The primary threat to any collection is chemical interaction. Common plastics, particularly those containing Polyvinyl Chloride (PVC), are chemically unstable. Over time, and accelerated by heat and humidity, these plastics leach chemical softeners (plasticizers) and can degrade to release hydrochloric acid gas. This process results in a corrosive green, sticky residue—often called "green slime"—that permanently etches the surface of a coin, causing pitting and irreparable damage.
Genuine Air-Tite capsules are engineered specifically to eliminate these risks. They are constructed not from common vinyl or polystyrene, but from a specialized, chemically inert acrylic (Polymethyl Methacrylate or PMMA) that is free of PVC and other damaging additives. This material is chosen for its exceptional long-term stability, optical clarity, and resistance to degradation, making it a standard in museum and conservation settings.
Furthermore, the distinctive black ring is not merely decorative; it is made from Volara™, an inert, cross-linked polyethylene foam that provides a secure, non-reactive cushion for the coin's edge. This dual-material system ensures that every part of the holder in contact with your coin is archivally safe and will not break down or cause harm over time. Choosing Air-Tite is an investment in scientific certainty and the long-term security of your collection.
The capsule's body is injection-molded from a custom-formulated, high-impact acrylic plastic. This material is not only chosen for its strength and durability but also for its superior optical properties. It is infused with a non-yellowing agent, ensuring that the capsule remains crystal clear for decades, never obscuring the intricate details or luster of your coin. Unlike cheaper polystyrene holders, which are more brittle and prone to scratching, this robust acrylic offers exceptional scratch resistance and provides a level of clarity comparable to glass without the associated risks of breakage. This ensures your coin is both perfectly protected and beautifully displayed.
The black ring included with this capsule is precision-cut from Volara™, a specialized, closed-cell, cross-linked polyethylene foam. In the world of archival conservation, a material's chemical stability is paramount. Volara™ is celebrated for being completely inert, meaning it is free of acids, PVC, and other chemical softeners that could tarnish or damage a coin's delicate surface over time.
The cover and base of the Air-Tite capsule are engineered to snap together with an exceptionally tight, secure seal. This precision fit is a hallmark of the Air-Tite brand, creating a formidable barrier against environmental threats. While no non-hermetic holder is completely "air-tight" in a scientific sense, the design significantly minimizes air exchange. This helps to protect the coin from humidity, airborne dust, and corrosive gases like sulfur, which are primary causes of toning and tarnishing. This secure closure ensures a stable microenvironment, preserving the coin's original mint state finish for the long term.
Properly encapsulating your coins is a critical step in their preservation. Following a consistent procedure will ensure that no contaminants are sealed inside the capsule, which could cause damage over time.
Begin by preparing a clean, well-lit workspace. Lay down a soft, non-abrasive surface, such as a velvet coin pad or a clean microfiber cloth. This will protect the coin and the capsule from scratches should they be accidentally dropped.
Never handle valuable coins with bare hands. The natural oils, acids, and moisture on your skin are corrosive to metal surfaces and can leave permanent fingerprints. Always wear clean, lint-free white cotton gloves or snug-fitting, powder-free nitrile gloves when handling both the coin and the capsule components.
