Guardhouse 2x2 Coin Flips for Half Dollars – 100 Pack Acid-Free Cardboard & Mylar Holders
Guardhouse 2x2 Coin Flips for Half Dollars – 100 Pack Acid-Free Cardboard & Mylar Holders
These Guardhouse 2x2 staple-shut coin holders are designed for half dollars and larger coins up to 30.6 mm. The pack includes 100 flips made from acid-free, museum-quality chipboard paper and Mylar, ensuring safe, long-term storage for coins of all metals and finishes.
What These Coin Holders Fit
Each holder measures 2 inches by 2 inches with a 0.1-inch thickness. The internal cutout accommodates coins with a diameter up to 30.6 mm, which covers U.S. half dollars (Kennedy, Franklin, Walking Liberty) as well as many world coins of similar size. The staple-shut design keeps the coin secure and easy to view without touching the surface.
Why Archival Materials Matter for Coin Storage
Guardhouse uses acid-free, museum-quality paper in these flips. Ordinary paper can contain acids that tarnish or discolor coins over time. The Mylar lining adds a transparent, inert barrier that protects the coin while allowing full visibility. This combination is trusted by collectors for long-term storage because it won’t react with silver, copper, nickel, or gold surfaces.
