how to store baseball cards in the attic

Places to store them include attics, garages, basements, closets, and storage units. For a variety of reasons, you should not store your cards in the attic. Attics are not climate controlled and this means temperatures can vary greatly.

If you must store your cards in the attic, make sure to properly preserve them. Carefully place them in card boxes. Card boxes should be kept in plastic storage bins, if possible, to protect the cards from moisture. The ideal place to store your cards would be in a climate-controlled storage unit or in a closet in your house so long as you have both a heater and air conditioner so that your house stays climate controlled.

If you do not have a good closet and cannot afford or do not want a storage unit, then the garage or basement are your only other options. The garage is more likely to get too hot than the basement. However, a basement is more likely to be damp than a garage. Whichever you choose, make sure you take the proper precautions to preserve your cards as best you can.
