Storage of a Coin Collection
The Environment of the entire Collection, or Group of Coins is the focus, taking into consideration Temperature, Humidity and Light. A relatively constant, moderate to low temperature and low humidity are preferable for long term storage of numismatic collectibles. Placing packets of silica gel, which absorbs moisture, in the coin storage areas helps control atmospheric humidity. The less light, the better; and absolutely no sunlight. This is why a safe or vault is ultimate storage container; because it controls Temperature, Light and Humidity, and provides Superior Safety. Groups of Coins, or Collections are best stored in plastic coin boxes, such as sold by PCGS, NGC and Whitman, and which will hold 20, separated, “slabbed” coins. Another alternative is a cardboard coin storage box (single and double; red, blue or black), which stack easily on each other. Different sizes are available for slabs, as well as Vinyl and Cardboard Flips.
