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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat These Coin Holders Fit\u003c\/h2\u003e\n\u003cp\u003eEach 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Archival Materials Matter for Coin Storage\u003c\/h2\u003e\n\u003cp\u003eGuardhouse 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.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGuardhouse\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHalf Dollar (Brown)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eChipboard Paper, Mylar\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduct Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2\" L × 2\" W × 0.1\" H\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eItem Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6.5 ounces (pack of 100)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePack Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 flips\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Coin Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 30.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eHow to Use and Organize with Standard 2x2 Systems\u003c\/h2\u003e\n\u003cp\u003eThese Guardhouse flips work with any standard 2x2 coin storage system.
