| These are increasingly in demand. Some investors prefer to proudly display their coins in archival folders, while others prefer airtight capsules, or mylar-lined carboard. Whatever you do, don't store yours in the PVC flips you often see in the marketplace. These are made from PVC which decomposes over time and destroys the coin it was to protect. In the event you obtain a coin already within such a sleeve, move it as quickly as possible to a better storage medium. You may consider Mylar, but realize that they are hard and might scratch the piece if isn't placed and taken out carefully. While they aren't airtight, they're reasonable choices for medium value coins that will be "left alone" for numerous years. |
