Buy Air Tite Model A - Direct Fit A24 Capsule - 24mm

Your set is not only metal, it is the investment of your time, emotions and resources. Do not leave its preservation to chance. Our Air-Tite Model A Direct Fit A24 capsule is an authentic product that provides museum quality, archival safe packaging which guarantees your 24mm sized coins will stay in mint condition - in brilliant shape - for many generations. This display is not just any case; it is an undertaking of protecting the beauty, integrity and value of your collection.

Why Choose the Air-Tite A24 Direct Fit Capsule?

When choosing a holder, discriminating collectors seek after certain qualities that ensure long term safety and best display. The air-Tite A24 is dominating in all the important categories.

Crystal-Clear, Unobstructed View

The capsules are injection-molded using a high-impact, virgin acrylic polymer, which gives them a crystal-clear, smooth-to-the-touch, hard surface finish. The Air-Tite holders do not turn yellow as do the inferior plastic holders, so you do not have an issue of viewing both sides of your coin at a later date being impaired. Such remarkable quality of clarity is key towards understanding the fine details of your coins without even having to take them out.

Archival-Safe for Long-Term Storage

The number one enemy of a coin in long term storage is its holder. Soft and flexible plastic flips and album covers have Polyvinyl chloride (PVC) and chemical plasticizers to make them soft and flexible. These plasticizers over time (and especially in the presence of heat or humidity) can migrate out, resulting in a corrosive, tacky green film commonly referred to as green slime. This forms hydrochloric acid, which chemically etches a coin, leading to microscopic pitting, cloudiness and irreversibly damaging the surface of a coin to the point that its numismatic value is greatly reduced. Air-Tite capsules are tested to be 100 percent free of PVC plasticizers and other hazardous plasticizers, rendering them chemically inert, and thus the professional source of archival-safe lasting protection.

Ultimate Protection Direct Fit Precision Direct Fit

The Direct Fit design is made to the precise 24.3 mm diameter of a coin such as the US Quarter. This close fit is very important because otherwise the coin would be mottled or would rattle in the holder. Any movement at all may produce micro-abrasions on the most elevated parts of the coin, a process called cabinet friction, and this will tend to reduce the luster and grade of an uncirculated coin over time. The Air-Tite A24 also keeps your coin well held in place, not deteriorating its delicate surfaces.

The Rugged and Scratch-Resistant Build

The lightweight acrylic casing has high impact resistance by absorbing shock in case of accidental drops and other normal handling. Should it fall, the heavy-duty vessel is supposed to take the blow, dying in order to save its precious cargo. It can as well resist a lot of scratches, and it can remain clear even when handled regularly.

Indeed, Made in the USA

Unlike most of the cheap imported plastic coin holders that one can find on the auction sites, Air-Tite capsules are manufactured in the United States. This dedication to domestic production means that the quality control standards are of the highest caliber, and that all manufactured capsules are contaminant free and meet the stringent specifications necessary to actually achieve archival storage.

The Collector's Guide: How to Use and Care for Your Air-Tite Capsules

Properly encapsulating and storing your coins is a critical step in preserving their value.

Proper Coin Handling Before Encapsulation

The natural oils and acids on human skin can cause permanent fingerprints and corrosion on a coin's surface. Professional numismatists often handle coins with clean, dry hands, holding them strictly by the edges. For collectors, wearing lint-free cotton or powder-free nitrile gloves provides an extra layer of security against accidental contact. Always work over a soft, padded surface, like a velvet tray or a thick towel, to prevent damage from accidental drops.

Step-by-Step Encapsulation Process

  1. Prepare a Clean Surface: Lay a soft, lint-free cloth on your workspace.
  2. Handle with Care: Put on your cotton or nitrile gloves.
  3. Position the Coin: Using only the edges, gently place your 24mm coin into the base (the shallower half) of the A24 capsule.
  4. Seal the Capsule: Place the cover (the deeper half) over the base. Press the two halves together firmly and evenly around the edge until you hear and feel a distinct "snap," indicating a secure, airtight seal.

How to Safely Open an Air-Tite Capsule

While designed for long-term storage, Air-Tite capsules can be opened without damaging the coin. Brute force methods like smashing them with a hammer are unnecessary and risk damaging the coin. The recommended method is to use a thin, sharp blade.

  • Hold the capsule firmly by its edges.
  • Carefully insert the tip of a utility knife or a thin pocket knife into the seam where the two halves meet.
  • Gently twist the blade to pry the seam apart slightly.
  • Repeat this process at several points around the circumference of the capsule until the lid loosens enough to be removed by hand.

Storing Your Encapsulated Coins

Once encapsulated, coins should be stored in a cool, dry, and stable environment to prevent the possibility of condensation and toning. Avoid attics, basements, or areas with significant temperature and humidity fluctuations. For superior organization and added protection, store your encapsulated coins in dedicated Air-Tite tubes or Guardhouse storage boxes. In humid climates, placing silica gel packets or other desiccants within your larger storage container (like a safe) can help create a protective microclimate by absorbing excess moisture.
