Ultra

The Ultra round capsules provide an individual protection solution for collectible coins. Made from high-clarity transparent plastic, they allow optimal viewing of both sides of the coin without requiring direct handling, thus preserving the surfaces of numismatic strikes against fingerprints, moisture and mechanical shocks.

These capsules consist of two snap-fit parts ? an upper cup and a lower cup ? that close by simple pressure, offering secure retention of the coin without the use of glue or any additional accessory. The integrated O-ring or clamping rim, depending on the model, ensures partial sealing against ambient air, slowing the natural oxidation of metal alloys.

Ultra capsules are available in several internal diameters, expressed in millimetres, in order to fit precisely the dimensions of the coins to be protected. It is essential to select the diameter corresponding exactly to that of the coin, measured edge to edge, to avoid excessive pressure on the relief or any play likely to cause friction.

This range covers a wide spectrum of common and collectible coins: euro coins of all denominations, silver coins such as Austrian Philharmonikers, American Silver Eagles, Britannias or Canadian Maple Leafs, as well as gold coins in standard formats. Sizes adapted to ancient coins, medals or tokens are also available in the range.

The material used is generally an optical-quality polystyrene or acrylic, free of PVC and plasticisers that could migrate to the metal surface and cause chemically induced spots. This characteristic is particularly important for the long-term preservation of coins in pure silver or gold.

Ultra round capsules are compatible with most standard numismatic storage systems: collection boxes, compartmentalised trays, binder dividers and presentation cases. Their flat cylindrical format facilitates stacking and storage in large quantities without risk of crushing or deformation.
