About Coin Capsules

Coin capsules are the global standard for protecting individual bullion and collector coins. Choosing the correct inner diameter is essential: too large and the coin moves and sustains edge damage; too small and it applies pressure to the rim. The 15 mm capsule is calibrated for coins of exactly that nominal diameter. The 15 mm size covers a range of small-denomination gold coins. The transparent material lets you inspect both sides of the coin without handling risk. Browse all capsule sizes, gold coins, and silver coins at GoldInvest24.

Frequently Asked Questions

Q: How do I measure my coin to select the right capsule size? A: Use digital callipers to measure the coin's outer edge in millimetres. Select the capsule whose inner diameter matches that figure for a snug, rattle-free fit.

Q: Can I reuse the capsule after opening it? A: Yes. The snap-fit lid is designed for repeated opening and closing without losing its sealing tension.

Q: Does the capsule protect against humidity? A: When properly closed, the capsule significantly reduces the coin's exposure to airborne moisture and dust, helping to maintain its condition over extended storage periods.

Q: Is the 15 mm capsule safe for proof coins? A: Yes — provided the inner diameter matches your coin precisely. The smooth inner rim will not damage delicate proof or frosted surfaces on a correctly sized coin.
