Square coin capsules QUADRUM int
Quadrum intercept - a square coin capsule with active start-up protection
QUADRUM intercept describes a whole new technology of coin collecting!
The material actively protects your coins from oxidation. The foam of this coin capsule is based on the intercept technology patented for over 30 years. The copper particles contained in the material permanently bind corrosive gases, forming a neutralized atmosphere, which protects the coins from the start in a very short time (guaranteed protection up to 15 years!). The effect has been demonstrated among other things according to proven standards EN, DIN, ISO and ASTM. Available for all coins from 14 to 41 mm in diameter (in mm increments)
