A pack of 10 ULTRA intercept ant tarnishing round coin capsules. ULTRA Intercept - the only round coin capsule worldwide with active protection against tarnishing! Thanks to proven technology, the coin capsules ULTRA Intercept offer a completely new kind of coin collecting. The foam ring inside the capsules with a thickness of 3 mm is based on the patented Intercept technology, which is proven for more than 30 years. The copper particles in the material bind corrosive gases permanently and as a result neutralise harmful atmospheric substances inside the capsule. This protects the coins from tarnishing. Guaranteed protection up to 15 years*! The effect was verified by the reliable norms DIN, EN, ISO and ASTM amongst others. Available for all coins with a diameter from 26 to 41 mm (in millimeter steps). External measurement of each of the capsules is 11mm more than the internal measurement i.e. 26mm internally measures 37mm externally.
