You do not need a bank vault to start — but you do need to avoid the mistakes that permanently damage coins and notes.
The enemies
- PVC in soft flips — eventually leaves a green film on metal.
- Humidity — toning can be pretty; corrosion is not.
- Cleaning — polishing or dipping destroys collector value.
- Bare fingers on bright surfaces — oils and tiny scratches add up.
Basic kit
- Archival flips or cardboard 2×2 holders (PVC-free).
- Plastic tubes for bulk bullion — labeled by type.
- A small safe or hidden, dry drawer — not the garage or attic.
- Cotton gloves or edge-only handling for nicer pieces.
Paper money
Store notes flat in Mylar-style holders or acid-free sleeves. Never rubber-band a stack; clips and folds are hard to reverse.
Insurance & records
Photograph your collection, keep purchase receipts, and talk to your homeowner insurer about a rider once value grows. A simple spreadsheet beats memory when something happens.
