The present invention relates to an apparatus and method for preserving one or more collectible items. The apparatus includes a housing and a nitrogen generator. A nitrogen generator generates a nitrogen rich gas and supplies the nitrogen gas to the housing, which displaces the oxygen inside the housing to preserve the collectible item or items enclosed by the housing. The nitrogen rich gas significantly reduces the degradation of the collectible item due to the exposure of the item to oxygen in the air. In another embodiment, the apparatus further includes a temperature control system and a humidity control system to control the temperature and humidity inside the housing. This further aids in preserving a collectible item for relatively long periods of time by reducing the effects of the environment on the item.
