Lighthouse (Leuchtturm) 37mm Coin Capsules are the definitive "direct-fit" protective solution for the Austrian Philharmonic series and several prominent historical European silver coins. As part of the professional "Grips" series, these capsules offer a crystal-clear, airtight environment designed to protect high-value precious metals from fingerprints, scratches, and environmental toning.
These capsules are engineered for collectors who require museum-grade preservation for large-format bullion and classic currency.
Premium Polyacrylic (PMMA): Made from extra-durable, scratch-resistant acrylic that is 100% free of PVC, acids, and chemical softeners. This ensures that your gold and silver coins remain in a chemically inert environment, preventing "milk spots" or unwanted tarnish.
Precision Airtight Seal: The two halves snap together with a mechanical lock that creates a protective barrier against humidity and atmospheric pollutants—essential for maintaining the brilliant finish of uncirculated silver.
Rimless Display: The "direct-fit" design allows the coin to fill the entire interior, providing an unobstructed 360-degree view of the design and the coin’s edge without the need for foam inserts.
Practical Handle Rim: Features a small notch on the outer rim for easy opening with a fingernail, while the locking mechanism is strong enough to stay closed even if accidentally dropped.
UV Protection: The high-grade acrylic is UV-stabilized to prevent yellowing or brittleness over time, ensuring your coin remains the focal point of your collection.
The 37mm size is a specialized diameter primarily used for specific European bullion and Latin Monetary Union standards.
