| These are increasingly in demand. Some collectors opt to proudly display their coins in archival folders, while others prefer airtight capsules, or mylar-lined 2x2's. Whatever you do, do not store yours in the PVC flips you frequently see on the market. They are made from PVC which breaks down over time and destroys the coin it was to preserve. Should you acquire a coin already in one of these, move it as soon as possible to something better. You might consider acetate flips, but recognize that these are hard and may scratch the coin if it is not inserted and removed with care. Although they aren't air-tight, they are alternatives for moderate priced coins that will be "left alone" for many a long time. |
