Accessories – Capsules, Tubes, Boxes & Etuis for Precious Metals

Anyone who invests in gold coins, gold bars, silver coins, or silver bars should also think about proper storage. Scratches, fingerprints, and oxidation can permanently affect the appearance — and therefore the resale value — of a coin. With the right accessories, you can protect your precious metals professionally, whether stored in a home safe, a collection album, or presented as a gift for a special occasion. CelticGold offers everything you need in one place: capsules, tubes, boxes, and etuis for almost every coin size and use case.

Coin Capsules – Protection for Individual Coins

Coin capsules are the most popular storage solution for individual bullion coins and collector pieces. The clear, hard-plastic capsules protect coins from handling, moisture, and oxidation without obscuring the fine detail of the struck design. Capsules are available in a wide range of diameters — from 21 mm for small gold coins to 80 mm for large silver coins or special strikes.

Finding the Right Capsule Size

The key factor is the outer diameter of the coin. A capsule that is too tight can damage the coin; one that is too loose allows movement and provides inadequate protection. The capsule's inner diameter should be slightly larger than the coin's diameter so the coin sits snugly but can still be removed without force. Here is a reference guide for the most common bullion coins:

Tubes – Space-Efficient Storage for Larger Quantities

Coin tubes are the most economical storage solution for investors who collect multiple coins of the same series or build up holdings regularly. A tube holds between 20 and 50 coins depending on size, protects them from dust and oxidation, and can be stacked efficiently in a safe. Tubes are particularly practical for building a growing coin collection or for investors who purchase 1 oz silver coins on a regular basis.

Boxes – Stylish Presentation and Safe Transport

Coin boxes offer not only protection but also an attractive presentation — ideal as gift packaging for gold coins or gold bars for birthdays, christenings, weddings, or anniversaries. High-quality boxes with velvet inlays give the gift an elegant setting and make the value of the precious metal immediately tangible.

Etuis – Premium Storage for Special Pieces

Etuis are the premium storage solution for particularly valuable or rare coins. They are frequently included by mints when coins are issued in proof quality (Polished Plate). A fitting etui preserves collector coins in perfect visual condition over the long term and provides safe storage for the accompanying certificate of authenticity. Proof coins from series such as the Vienna Philharmonic or Maple Leaf are typically delivered in their original etui and should always be kept in it.

Why Proper Storage Matters

Bullion coins and collector pieces are graded on condition at the point of resale. A coin in original condition — free from fingerprints, scratches, or oxidation — will consistently command a better price than a damaged one. This is especially relevant for high-value series such as the Vienna Philharmonic, Maple Leaf, or limited-edition coins, where proper storage can have a meaningful impact on long-term value preservation.

Gold and silver coins should never be touched with bare fingers — always hold them by the edge or use cotton gloves. Combining a coin capsule with a sturdy box or etui provides the best possible long-term protection.

FAQ – Frequently Asked Questions About Coin Accessories

Which capsule fits my coin? The key measurement is the coin's outer diameter in millimetres. Choose a capsule with an inner diameter that is slightly larger than the coin. If in doubt, our customer service team can recommend the right size.

Are coin capsules suitable for both gold and silver? Yes. Clear, acid-free plastic capsules are suitable for both gold coins and silver coins. For silver, pay particular attention to airtight capsules, as silver is more susceptible to tarnishing through contact with airborne sulphur compounds.

Can I order accessories together with precious metals? Yes. Accessories and precious metals can be added to the same cart and shipped together in a single insured order.

Are boxes and etuis suitable as gift packaging? Absolutely. Boxes and etuis are ideal for presenting gold coins or gold bars as gifts — for christenings, birthdays, graduations, or weddings. For more gift ideas, visit our blog.

How should I handle my coins to avoid damage? Always hold coins by the edge and avoid touching the face or reverse with bare fingers. The natural oils from skin can cause fingerprint marks that are difficult to remove without risking further damage.
