Buying Guide: Key Purchase Considerations
- Coin size compatibility: Measure the coin’s diameter and depth to select an appropriate capsule size. Most 1 oz coins sit in the 32.7 mm–33 mm range with a 3.17 mm depth.
- Seal quality: Air-Tite and other reputable brands emphasize air-tight, scratch-resistant materials. A tight seal helps prevent tarnish and corrosion over time.
- Visibility vs. protection: Clear acrylic or plastic provides visibility for display. For long-term storage, ensure the material resists yellowing and haze and won’t abrade surfaces.
- Assembly and ease of use: Some capsules ship unassembled; consider whether quick assembly is a priority for your storage workflow.
- Display vs. storage needs: Slab boxes and display holders are ideal for shows or exhibitions; inline capsules are better for secure, space-efficient storage.
- Compatibility with mixed coins: If you own various sizes (e.g., 1 oz platinum, 1 oz gold), choose a modular system or a range of sizes to cover each coin type.
- Durability and handling: Look for sturdy edges, smooth rims, and secure closures to minimize scratching during insertion or removal.
