Quadrum Capsules

The Quadrum capsules for 2 euro coins are rigid individual protections specifically designed for the format of standard and commemorative 2 ? coins, with a standard diameter of 25.75 mm. Made from high-transparency acrylic plastic, they consist of two snap-fit parts that hold the coin without direct contact with the walls, thanks to an inner O-ring.

This pressure-lock closure system provides optimal protection against humidity, dust and handling, while allowing both sides of the coin to be viewed without removing the capsule. The clarity of the material ensures faithful reproduction of striking details, reliefs and surface nuances, whether for bimetallic coins intended for circulation or superior quality strikes.

Quadrum capsules are compatible with standard boxes, trays and binders with compartments used in numismatic conservation. Their standardised square format facilitates the storage and organisation of collections of 2 euro coins from eurozone countries, whether national series, common programme commemoratives or special strikes issued in limited quantities.

The anti-UV acrylic material used in the manufacture of Quadrum capsules helps to limit the deterioration of metal surfaces caused by prolonged light exposure, thus preserving the conservation condition and numismatic value of stored coins. These capsules are suitable for storing coins in both Proof (FDC) and Brilliant Uncirculated (BU) condition.
