QUADRUM Intercept - The square coin capsule with active protection agains tarnishing
QUADRUM Intercept represents a completely new technology for the coin collection!
The material protects your coins actively from tarnishing. For over 30 years, the patented Intercept technology describes this process which is based on the special foam insert in the QUADRUM coin capsule. 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.
