Dansco's archival Slipcase is manufactured with Silver-Guard Corrosion-Inhibiting protection. A Military Specification material neutralizes corrosive gases in the air that can cause toning and discolorization.

 This is a barrier product designed to assist in the long term storage protection of your coins, it will not reverse the effect of existing toning, or poor handling of coins and collectibles prior to the use of this product. Please note: even with this product we encourage collectors to keep their collectibles in a cool, dry place away from extreme temperature changes and fluctuations from humidity.
