Leuchtturm Matrix Self-Adhesive Coin Holder for 20 mm Coin

Leuchtturm Matrix 20 mm self-adhesive coin holder

The white Leuchtturm Matrix holder is designed to store and display a coin up to 20 mm in diameter without repeatedly removing it. A sturdy card frame supports the coin, while clear windows let you examine both sides. It is a practical way to organise circulation, commemorative and collectible coins while reducing unnecessary handling during routine viewing.

50 × 50 mm card with plasticiser-free film

The holder measures 50 × 50 mm on the outside. Its white card border provides room to note a country, date, denomination or catalogue number. The viewing film is anti-glare and free from chemical plasticisers. It keeps coin details visible while separating the surfaces from fingers and dust during normal collection handling.

How to close a Matrix holder

Measure the coin’s actual diameter first and select the matching opening. Place the coin in the open holder, fold the two sides together and press around the border to activate the self-adhesive closure. No staples or separate glue are needed. Handling the coin by its edge, or using suitable numismatic gloves, helps avoid fingerprints.

A clear system for a coin collection

The consistent square format makes these holders easy to arrange in matching album pages and storage boxes. The white frame offers a tidy backdrop and a place for identification notes, so a particular date or variety is easier to find later. This version is intended for coins no larger than 20 mm; check the coin itself rather than relying only on its denomination.
