Quadrum-style coin case). It is a numismatic protective holder used by collectors to store, display, and protect valuable coins, bullion rounds, or medals from dust, scratches, moisture, and oxidation.
How it works:
- The Case: The outer shell is made of two halves of rigid, crystal-clear, archival-grade acrylic or plastic that snap together tightly to form a protective seal.
- The Gasket: The black square section contains a dense, acid-free foam insert or gasket. Many variants come with punch-out rings or flexible inner borders so that you can cleanly fit coins of varying millimeters (such as 18mm to 40mm) tightly in the center. [1,
