Archival quality protection made especially for older, small ANACS holders (for the new larger holders, use the PCGS/NGC track box). Both the lid and the box itself are lined with Corrosion Intercept. The box securly holds 20 ANACS encapsulated coins. Note that this box does not have the inner boxes (like the double protection boxes) but that the coins cannot move around inside the box. Box dimensions are 10-7/8" by 2-1/2" by 2-7/8". Intercept Shield acts as a neutralizing agent cleansing the air around the coin protecting it from the harmful effects of corrosion.
