What is the primary distinction between the Air-Tite Model X6D when compared to other models such as the X or I?

The main contrast is the inner depth. It is an 11.2mm or greater (when measured internally) or a high relief and extra deep capsule, with an internal depth of 7.2mm. It is compared with the normal Model X, a depth of about 3.96mm and Model I, a depth of about 2.92mm. The X6D is specially made to accommodate extremely thick coins and medallions that would not fit in or would rattle inside the shallower capsules.

Does my 2 oz Queen s Beast coin have a chance of rattling around in this x6D-38mm capsule?

No, it will not. Collectors are well aware of this capsule being the perfect match to the 2 oz Silver Queen Beasts series. Its depth of 7.2mm is optimized to accommodate the coin with its high relief as well as thickness ensuring a firm and tight fit to where the coin is unable to move freely and rattle around as is the case when these coins are inserted into standard holders.

And how do I get a Air-Tite capsule open, without ruining the capsule or the coin?

Air-Tite capsules have been made very tight by making the sealing extremely tight, thus harder to open using fingernails alone. The best suggestions: a thin, not overly sharp tool that would be a pocket knife, utility knife, or spudger especially made out of plastic. The tip of the blade should be inserted into the seam between two half carefully and then it should be given slight twist. Go all the way around the circumference of the capsule and pry a little at some places. When a small space is opened up, one should then be able to part the two pieces together with your fingers. When carefully performed, this procedure will have no damage to the capsule or the coin inside.

Are the black foam rings in Air-Tite capsules safe for long-term contact with my coins?

Yes, absolutely. The foam rings used in genuine Air-Tite capsules are made from an inert, cross-linked polyethylene material called Volara. This material is archival safe, contains no PVC or other harmful chemicals, and will not tarnish, discolor, or damage your coins, even with direct contact over many decades.

What is PVC damage and why is it destructive to coins?

Polyvinyl chloride also known as PVC is a plastic commonly found in soft flexible coin flips. It is made flexible by the introduction of chemical softeners known as plasticizers. These plasticizers can over time and in the humid and hot conditions, leach out of the plastic and onto the surface of the coin. This leaves a sticky, green, or milky residue, usually referred to as green slime, and this is an acid that will corrode the metal and leave lasting pitting and etching that may ruin a coin in terms of its numismatic value.

Does every plastic coin holder pose no harm? What am I supposed to search?

No, not every plastic is safe to keep coins long term. Most significant among them is to make sure that the holder is 100% PVC free. Hard, inert plastics, such as acrylic (polystyrene) and polyester (commonly marketed under the trade name Mylar) are the safest and most popular materials used in archival storage. On any material that you are considering buying as storage always seek to find clear indicators such as PVC-Free and Archival Safe on the material which will provide the greatest safeguard to your collection even in the long run.

Do I need to use gloves when handling my precious metal coins?

There is some controversy as to this but in order to be safe with the collection it is best to wear gloves. Although most professional numismatists and graders wash their hands and handle coins using dry hands, being careful to handle coins only by the edges, this takes a great deal of practice and skill. In the case of the collector, cotton gloves are recommended when handling a coin, lint-free and clean as possible to prevent any risk of making contact with the coin, which will cause the dangerous oils present in your fingerprint to transfer to the coin surface. It is also advised not to use latex or powdered gloves, because this type of gloves may contain lubricants and chemicals that are harmful to coins as well.

What is the difference between a "Ring-Fit" and a "Direct-Fit" coin capsule?

A Direct-Fit capsule is precision-molded to the exact diameter and standard thickness of a specific, common coin, like an American Silver Eagle (40.6mm). It holds the coin snugly without any inserts. A Ring-Fit capsule, like this Model X6D, uses a soft, inert foam ring inside a larger universal capsule shell. This design offers greater versatility, allowing a single capsule model to securely hold coins of slightly different diameters. The ring also provides an attractive border and an additional barrier against air contamination.

Air Tite Model X - Black Ring Capsule - X6D-38mm

Buy Air Tite Model X - Black Ring Capsule - X6D-38mm

The Ultimate Archival Protection for Your High-Relief 38mm Coins

Eliminate the rattle and avoid marring your largest coins. Gold, silver and platinum are thick and high-relief, which means that standard capsules just will not fit snugly, such as in the case of the Queen Beast series with 2 oz of Silver or the Canadian Wildlife medallions in 1.5 oz. The Air-Tite Model X Black Ring Capsule (X6D-38mm) it is the purpose made solution to any goal, and one that has been designed with a lot of extra depth to provide a secure, archival-quality fit that keeps the value and pristine beauty of whatever is most important to you, safe and secure.

Key Benefits

High-Relief Fit: An ultra-deep 7.2mm internal depth removes the movement and rattle, giving a snug housing to large thick 2 oz silver coins, 1.5 oz medallions that does not fit in standard holders.

High Grade Materials: Proudly US-made of crystal-clear non-yellow acrylic. 100% PVC and other harmful plasticizer-free capsules will guarantee that your assortment is safe to be kept in over the course of several years, across generations.

Improved Aesthetic Presentation: The added inert black foam ring provides a beautiful contrast that will bring out the beautiful details on your silver and gold coins, making your coin stand out.

Safe & Airtight Capsule: This precision-molded, two-piece snap capsule is airtight and forms a tight secure seal that protects your coins against airborne contaminants, humidity and corrosive oils caused by accidental handling.

The X6D Advantage: Engineered for Your Most Substantial Coins

The Model X6D capsule is the feature that is the most distinctive due to its unprecedented depth. Whereas typical coin capsules have an interior depth of about 3mm, the X6D is cavernous at 7.2mm of clearance. This extra room is no coincidence, it is deliberately designed to accommodate the dramatic, high-relief strikes of modern bullion coins, including the 2 oz Queen Beast series of coins at the British Royal Mint which have proven to be very popular. Placing these coins in an ordinary capsule would cause a loose rattling fit, which can be abrasive and leave contact marks after time and this can potentially lower a coin in its grade and value. The X6D does away with this risk, and offers a tight, safe space.

Not All Plastics Are Created Equal: The Importance of Archival-Safe Acrylic

Plastics comprising of Polyvinyl Chloride (PVC) have long been dreaded by collectors, due to their irreparable nature of damages. Coins placed in PVC holders may accumulate a sticky, green residue which forms on the surface of the metal, effectively ruining the numismatic value of the coins since it is irreversible.

Real Air-Tite capsules are made out of a totally different material: a hard, clear acrylic, which is chemically inert, 100 % PVC free. This archival quality material lacks the damaging plasticizers found in PVC materials. It also contains a non-yellow agent so your impression of the coin is always lovely and clear even decades later, so it is the gold standard of long term protection.

Handling and Assembly Guide

You need to take care of your coin to ensure that you keep it in mint condition. We advise the use of clean, lint free cotton gloves to avoid letting corrosive oils on your skin to come in contact with the surface of the coin.
Never touch your coin with its face and obverse and reverse, but only on the sides which have the reeds.
Carefully insert the coin into the black foam ring, which is already placed into the base (which is the deeper half) of the capsule.
Place the cover on top of the base.
Tighten at the edges as much as possible, and as evenly as you can get them, until you hear and feel a sharp snap. This sound assures a water tight, air tight seal on your investment sealing it off the elements.
