Numismatic pouches and bags

Numismatic pouches and bags are flexible storage solutions designed for the preservation and handling of coins, banknotes, medals and other collectibles. Made from neutral materials such as polyethylene, polypropylene or Mylar, these containers are engineered to avoid any chemical interaction with metal surfaces or paper substrates, ensuring the long-term integrity of coins.

Numismatic pouches come in several standardised formats, suited to the common dimensions of coins from around the world, from small 10 mm pieces to large silver coins of 50 mm and above. Some models feature a zip or flap closure, allowing repeated opening and closing without damaging the container or its contents.

Hermetically sealed bags provide additional protection against moisture, dust and oxidising agents present in the atmosphere. They are particularly recommended for storing silver coins prone to tarnishing, as well as copper and bronze coins at risk of verdigris or corrosion.

Transparent pouches allow immediate visual identification of the coin without having to remove it from its container, limiting direct handling and reducing the risk of scratches or fingerprints on surfaces. This transparency is especially useful when sorting, taking inventory or displaying a collection.

Available individually or in bulk quantities, these pouches and bags cater to both private collectors and professional numismatists, museums and heritage institutions. Their lightness and flexibility also make them practical supports for the secure transport of coins at fairs, exchanges or transactions.

The choice of material is crucial: PVC pouches should be avoided for long-term preservation due to the plasticisers they contain, which can migrate onto coin surfaces and leave permanent marks. Acid-free and PVC-free materials are systematically preferred for any serious conservation purpose.
