Knowing how to use coin capsules right prevents the classics—rim dings from forcing, dust trapped under the lid, and assuming «closed» means sealed when the ring is twisted.
Steps are simple but non-negotiable: match diameter, seat with even pressure (or thread per model), confirm no rattle, and stop reopening every week.
Seating without rim dings
- Glove or plastic tips—never push with a fingernail on the face.
- Halves aligned: if threaded, turn without tilting the coin.
- Listen for a clean click; crunch = grit or wrong size.
Closure and microclimate
After closing, dust the outside—do not pop daily «just to check». Near oceans, store capsules in silica boxes, not bathrooms.
