What Causes Silver to Tarnish?
Silver cannot rust but silver can tarnish.
While rust only occurs with iron and iron-based metals, tarnished silver is still an eyesore.
A chemical reaction occurs when silver comes in contact with sulfur compounds in the air. This reaction produces a layer of sulfur dioxide on your coin’s surface, which appears as a discoloration making the silver look dull and tarnished.
Other factors, including moisture, humidity, and high temperatures, contribute to tarnish. Contact with chemicals found in cleaning products can also tarnish your silver coin.
Should I Keep My Coins in APMEX Flips?
Keeping your silver coins in the flips you receive them in is typically recommended. They provide a layer of protection against the surrounding environment, which helps to minimize dings, scratches, and other damage to the coin’s surface.
Equally important is coin flips’ protection against humidity, heat, and sunlight. Keeping your coins in high-quality flips is a trusted way to preserve their appearance over time.
You can do a Few Things to Minimize Tarnish in Your Silver Collection.
Store your silver in a cool, dry place. Moisture and humidity can accelerate the tarnishing process.
Keep your silver away from direct sunlight, which can also accelerate tarnishing.
Do not touch your silver bare-handed. Even with cotton gloves on, avoid over-handling your silver coins.
Keep silica packets or desiccants in the area near your coin collection to absorb excess moisture.
Never try to clean your coins. Leave this step to professional organizations like PCGS and NGC.
