Abstract
Abstract A container has a tubular container portion closed at one end and open at the other and of a length to receive a predetermined number of copper or silver coins and loosely confine them as a stack. A cap closes the open end of the container portion and is secured thereto and has within it a body of a corrosion inhibiting agent inert with respect to copper and silver and an insert between the body and the upper end of the tubular portion. The insert has ports through which gas may escape but which are closed by a releasable seal until coins are to be stored in the container and the insert holds the coins against blocking the ports.
