Junk Silver Coins

Junk silver coins are all silver coins that have not numismatic value other than the value of silver metal in them. Collectors in United States, Australia, Canada, and United Kingdom use the term junk silver for these coins. The word junk defines the collectible value of such silver coins. Most junk silver coins contain 90 percent silver by weight and some contain 30 to 45 percent silver by weight. Many collectors are not interested in junk silver because people use them as everyday currency. They look for uncirculated junk silver coins. These uncirculated coins have both collectors' value and silver content value. Junk silver coins derive their value only from their silver content, and they have no rare or collectible value otherwise.

Investors often invest in precious metals such as gold and silver because they retain their value during times of economic instability. Junk silver is an easy and low cost investment option. It retains its face value irrespective of the value of silver. Most buyers consider dollars, half dollars and dimes as the best junk silver coins to collect.

How to Clean Junk Silver Coins

Collectors should never clean coins that have a collectible value greater than

the value of the metal or alloy, because cleaning can cause microscopic abrasions on the coins and reduces their value. Experts call the tarnish on valuable coins "patina" or "toning." Buyers often clean circulated junk silver coins because the coins are worth as much as the value of silver content in them. Here are some ways to clean junk silver coins.

Clean the Tarnish

Lay a square piece of aluminum foil at the bottom of a stainless steel pan. Fill the pan with a few inches of water, and bring it to a boil. Turn off the burner when the water is boiling hot. Alternatively, lay aluminum foil in a plastic or any non-metallic container and pour boiling water into it. Add half a cup of baking soda and a tablespoon of salt into the pan or container. Put the coins into this solution on the foil in a single layer. All the tarnish from the coins disappears after the baking soda causes a chemical reaction that transfers the tarnish from the coin to the aluminum foil.

Clean the Grime

Take coins with grime deposits to the sink. Scrub each coin individually under the faucet with baking soda and water. Use thumb and fingers to rub the coins with baking soda paste. Use an old toothbrush with soft bristles to clear grime from the nooks. Baking soda is a very soft abrasive and causes no damage to the coins. Dry the coins with a towel or a soft jeweler's cloth.

Clean Stubborn Stains

Place the coins in a jar of liquid silver cleaner for fifteen minutes. Read instructions on the silver cleaner container and follow the time accordingly. Some collectors place the coins in lemon juice for an hour and rub them with fingers and a towel afterwards to clear the stains.
