Coin Cases

Numismatic cases are individual containers designed for the preservation and display of collectible coins, medals and tokens. Made from a variety of materials such as velvet, faux leather, lacquered wood or fabric-covered cardboard, they provide appropriate protection for the most fragile specimens as well as high-value pieces.

A coin case differs from a box by its single-unit format: it typically holds one coin, one medal or a limited set, in a padded housing that keeps the specimen in place without direct contact with abrasive surfaces. The interior is most often lined with cut foam, satin or velvet, inert materials that do not alter metal surfaces or patinas.

Cases are available in many standardised formats corresponding to common coin diameters: small sizes for fractional gold coins and regular coinage, intermediate formats for 1 to 2 ounce coins, and large formats for commemorative medals, large-module coins or prestige coins struck by the world's major mints.

Some cases are specifically designed to accommodate coins encapsulated in certification slabs issued by services such as NGC (Numismatic Guaranty Company) or PCGS (Professional Coin Grading Service). These adapted containers allow graded specimens to be stored and displayed while preserving their certification.

The choice of a case depends on several technical criteria: dimensional compatibility with the specimen to be preserved, the quality of interior materials (absence of sulphurous or acidic compounds that could cause chemical reactions on metal surfaces), and the strength of the closure, which determines long-term mechanical protection.

Cases with transparent windows allow the coin to be observed without removal, thanks to a lid incorporating a rigid plastic or glass panel. This type of presentation is particularly used for commemorative coins, limited edition pieces or specimens intended to be presented at institutional or ceremonial events.

Numismatic cases are aimed at both private collectors wishing to showcase specific acquisitions and at official mints, auction houses and coin dealers who use them for the presentation of specimens for sale or exhibition. Their role is twofold: to ensure storage under controlled conditions and to provide a sober and professional presentation setting.
