Some display cases also come with adjustable partitions that allow the coins to be stored in separate compartments, further reducing the risk of tarnish and damage.
When cleaning and handling the coins before storing them in a display case or jewelry box, always use gloves to prevent oils from your skin from coming into contact with the coins.
