Frequently Asked Questions

Q: What size coins fit in these 40mm coin capsules?

A: These coin capsules feature a 40mm inner diameter, making them suitable for large coins such as US Morgan silver dollars, Peace dollars, American Silver Eagles, and many large international coins. Always measure your coin's diameter before purchasing to ensure a proper fit.

Q: Are these capsules airtight to protect against moisture?

A: The snap-lock closure creates a tight seal that significantly reduces exposure to moisture, dust, and airborne contaminants. While they provide strong everyday protection, they are not laboratory-certified airtight containers. For long-term archival storage, keep capsules in a cool, dry environment.

Q: Can these coin capsules be stacked or used in a coin storage box?

A: Yes! These capsules are designed to be compatible with standard coin storage boxes and trays, and they can be stacked neatly for space-efficient organization. They are a great addition to any numismatic storage system.

Q: Is the plastic safe for coins and won't cause toning or damage?

A: The capsules are made from clear plastic that does not contain PVC, which is known to cause toning and damage to coins over time. This makes them a safe and reliable choice for protecting your collection.
