| These are growing in demand. Some investors like to proudly display their coins in archival folders, while others like airtight capsules, or mylar-lined 2x2's. Whatever you do, don't store yours in the soft flips you frequently see on the marketplace. They are made from polyvinyl chloride which decomposes over time and destroys the piece it was to protect. In the event you obtain coins already in such a sleeve, transfer it as soon as possible to a better storage medium. You may consider Mylar, but understand that they are hard and may scuff the piece if isn't inserted and taken out carefully. Although they are not air-tight, they're alternatives for moderate priced coins that will be "left alone" for numerous years. |
