Care

A cleaned coin is usually a damaged coin. Toothpaste, vinegar, baking soda, brushes, and polish cut the surface.

Do

• Hold a coin by the edge.
• Rinse loose dirt with distilled water and dry in air. No soap. No rub.
• Store in an archival album or a capsule. Keep silica in the box, not in the capsule.
• Lay notes flat. Do not fold a fancy serial.

Do not

• Do not clean, dip, or polish a coin.
• Do not use a PVC flip. It sweats and stains.
• Do not leave a note in sun or in a fold.
• Do not treat a catalogue value as an offer.
