Yes, but just seal the bags, do not vacuum them. The pressure caused by the vacuum can cause the pages and print transfers to stick together. Coins can be vacuum-packed, but be sure that you place some type of backing, such as cardboard, in the bag against the "waffle" side, and face the coins toward the smooth side of the bag. This will eliminate the possibility of any marks left on the coins after long term storage.

You should also put any printed materials between cardboard or in an archival sleeve before vacuuming. Otherwise the printing may transfer to the bag if you ever remove the material from the bag. We cannot guarantee the preservation of any items you choose to vacuum package.
