| These are growing in demand. Some investors like to proudly showcase their coins in archival folders, while others prefer airtight capsules, or mylar-lined 2x2's. Whatever you choose, don't store yours in the PVC flips you frequently see on the marketplace. They are made from PVC which breaks down over time and destroys the piece it was intended to preserve. Should you buy coins already in one of these, move it as quickly as possible to something better. You may consider Mylar, but recognize that these are hard and might scratch the coin if it is not placed and taken out carefully. Although they are not airtight, they are alternatives for moderate priced coins that will untouched for numerous years. |
