QUADRUM Intercept - The square coin capsule with active protection against tarnishing. QUADRUM Intercept represents a completely new technology for coin collection!

The material protects your coins actively from tarnishing. For over 30 years, the patented Intercept technology has described 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 standards DIN, EN, ISO, and ASTM, among others.

Overall size: 50 x 50 x 6.25 mm

*The effect duration will significantly exceed the specified 15 years under normal storage conditions! Very unfavorable conditions (e.g., exceptionally high air pollution or the constant opening of the capsules/boxes) could cause the effectiveness of the Intercept materials to be used up prior to the 15 years. When the potential of the material has been exhausted, the film will turn a dark grey to green color (not the coins!). When this discoloration occurs, you should replace the product with a new one.
