Why PVC-free coin storage matters
Not all coin holders are equal. The single most important thing to check before you store a coin is whether the holder is free of PVC. Cheap flips and sleeves are often made with it, and over months and years it can do real, sometimes permanent, damage.
What PVC does to coins
PVC, polyvinyl chloride, is made flexible by adding plasticisers. Over time those plasticisers migrate out of the plastic and settle on whatever they touch. On a coin this shows as a greenish, slightly sticky film, often called PVC contamination or 'green slime'. On silver and copper especially, it can etch the surface and leave marks that no gentle cleaning will remove, lowering both the appearance and the value of the coin.
Why acrylic is different
Our capsules are hard, crystal-clear acrylic made with a non-yellowing agent and no PVC. Acrylic is inert: it does not off-gas plasticisers, does not react with metal, and does not cloud or yellow with age. That makes it suitable for long-term, archival storage, the kind you want for bullion and collectable coins you intend to keep for years.
Good practice alongside a good capsule
A capsule protects the coin, but handling and environment matter too. Always hold coins by the edge, store them somewhere cool and dry away from direct sunlight, and avoid wiping or polishing collectable coins, which can scratch them and reduce their value. A sealed acrylic capsule keeps fingerprints, humidity and airborne pollutants off the surface, which is the best routine protection you can give a coin. See how to store a coin collection for more.
