Ultra Perfect Fit

The Ultra Perfect Fit capsules are individual protective cases designed for the storage of collectible coins. They consist of two rigid plastic parts that snap together, holding the coin firmly without direct finger contact during handling.

The inner diameter of each capsule is calculated to the nearest tenth of a millimetre in order to fit exactly around the coin it is intended to hold. This tight tolerance eliminates any lateral play, preventing micro-movements that could cause friction on the coin's relief or fields.

The round Ultra Perfect Fit capsules are made from high-clarity transparent plastic, generally polystyrene or acrylic, allowing both sides of the coin to be viewed without opening the capsule. The transparency of the material produces no notable visual distortion, making it easy to examine the strike details, reliefs and state of preservation.

This type of capsule is available in a wide range of diameters to suit common coins and world coins: euros, francs, dollars, crowns, thalers and many other series. Each diameter reference corresponds to one or more specific coin types, which means you must know the exact diameter of the coin to be protected before placing an order.

The Ultra Perfect Fit capsules are compatible with most numismatic storage trays with round compartments, as well as standard binders and presentation boxes. Their secure snap-fit allows vertical or horizontal storage without risk of accidental opening.

The material used in the manufacture of these capsules is selected for its chemical neutrality: it does not release sulphurous or acidic compounds that could alter the metallic surfaces of coins, whether silver, gold, copper, bronze or other alloys. This property is essential for the long-term preservation of collectible coins, particularly those in Mint State (MS) or Proof condition.

Capsules are generally offered individually or in lots, depending on the available diameters. It is recommended to verify the official diameter of each coin with the issuing mint or a reliable numismatic reference source in order to select the correct capsule size and take full advantage of the precise fitting system specific to the Ultra Perfect Fit format.
