Hartberger Cases and Sleeves for Coins and Medals

The Hartberger cases and sleeves are individual protective solutions designed for the storage and presentation of coins, medals and other numismatic collectibles. Manufactured by Hartberger, a well-known Dutch manufacturer in the field of numismatic supplies, these products meet the requirements of both professional and amateur collectors.

The Hartberger sleeves are made from chemically neutral materials, guaranteeing no reaction with precious metals and common alloys. This essential feature preserves the integrity of coins over the long term, preventing any surface alteration caused by outgassing or residual acidity in the material.

The range includes rigid cases and flexible sleeves, available in numerous formats suited to different standard coin diameters and both common and collector coins. The dimensions cover everything from small 14 mm coins to large medals or extended-format coins.

The Hartberger rigid cases are generally presented as transparent double-sided holders, allowing both sides of the coin to be viewed without direct handling. This design helps to minimise the risk of fingerprints and mechanical wear on the relief surfaces.

The Hartberger flexible sleeves, on the other hand, offer a lightweight and practical alternative for storage or transport. Transparent and resealable, they allow quick identification of the contents while providing protection against dust, ambient humidity and minor shocks.

These supplies are compatible with Hartberger binders and albums, enabling a consistent and uniform organisation of a collection. The cases can be inserted into punched sheets or storage trays specific to the Hartberger format.

The entire Hartberger cases and sleeves range is particularly suited to the preservation of euro coins, ancient coins, commemorative coins, and coins in precious metals such as gold and silver. The packaging is generally offered in bags or boxes containing several units, making it easy to stock up in quantity for regular collectors or professionals in the numismatic sector.
