Slabs offer excellent long-term protection but they are expensive and are generally used to store only very valuable coins. Handling Coins Improper and frequent handling of coins can significantly diminish their numismatic value. Handle coins only when absolutely necessary and in accordance with the guidelines set out below. Avoid touching the surface of a coin with your fingers. Coins should always be held by their edges.
Fingertips contain acids that can damage the surface of a coin.
When viewing a coin, always place it a soft surface such as a felt pad. Dropping a coin on a hard surface can result in nicks or scratches. If coins are being shipped it is important to package them properly so that the coins cannot bang into each other. Ideally, each coin should be packaged individually with appropriate padding.
