Very heavy duty white box made for baseball cards but works just fine for certified coins as well. Box and lid are lined with Corrosion Intercept. Holds approximately 30 certified coins. Note that this box does not include the inner boxes like the double protection box. It is intended for shorter term storage (e.g., dealer inventory). Dimensions are 12-1/2" by 2-7/8" by 3-5/8". Intercept Shield acts as a neutralizing agent cleansing the air around the coin protecting it from the harmful effects of corrosion.
