Matt Chappell - 6th September Old coins are not just fun collectable items, they can also be extremely valuable. The best way to clean old coins is, incredibly, to not clean them at all! Your first instinct, if you collect or want to sell old coins , might be to try to get them as shiny and beautiful looking as possible. Coins are graded by collectors due to a number of different factors, from the rarity of the coin, to the date, to the mint where it was produced, and of course the condition of the coin.

But the condition of the coin is classified as wear and dents, not the superficial aesthetics such as dirt and grime. Patina, that green film that forms on old metals due to exposure over the years, is actually desired and appreciated by avid coin collectors. It is best not to clean rare coins as removing the patina can significantly reduce the value of them.

For this reason, most coin hobbyists almost never clean their coins. If you really insist on trying to tidy up your coin collection, a very light brushing, or possibly a quick rinse with water is the absolute limit of what you should attempt.

Do not rub coins, just let them dry naturally in the air. Coins all shiny from using brass or silver polish will have actually lost much of their value.

Copper, silver, nickel, and gold coins should strictly never be cleaned. But if you do really want to get stuck in and have a go at cleaning some coins, we recommend that you experiment on some modern loose change instead.

Something like a penny for example. Simply place one coin in a glass or tub and pour coke over the top, enough so that it is fully submerged in the liquid. Leave the coin to soak for about 5 minutes or so and then check on its condition. If you feel that it needs longer, you can soak it for up to 15 minutes. Next, carefully pat it dry and leave it to fully dry naturally on a windowsill or similar. Warning — do not mix coins together when they are soaking in the Coke, as some coins may discolor other coins.

Hereof, can Coca Cola clean a penny? Coke and off-brand colas will quickly remove the tarnish. Just don't drink the coke afterward. Coke contains phosphoric acid that cleans the oxides.

Try a variety of citrus juices to see which works best or simply let your pennies soak in lemon juice. Secondly, how long does it take to clean a penny with Coke? Soak pennies for about 24 hours. Remove from the Coca- Cola and rinse with water. Avoid rubbing the coin as it's being rinsed because this can scratch it. Soak the coin in a small bowl of Coke for approximately 5 minutes. Rinse the coin again under cold running water. If it's clean , proceed to the drying step, No.

When the copper oxide the pennies and the phosphoric acid the cola get together in the bath, the acid reacts with the copper oxide on the pennies and dissolves it. That's why the pennies get shiny. Wash the coin off in hot water. Why do pennies turn black? Because zinc tends to corrode more quickly than copper, newer pennies tend to form darker green or black layers as they corrode.

It occurs when the copper-hydroxide-carbonate on the penny's surface reacts further with oxygen and moisture in the air to form copper sulfides. Should you clean wheat pennies? Sure, you can put scratches on a penny if you scrub it too hard. These wheat pennies are so encrusted that they will never be cleaned to the point that they have eye appeal.

You lose some, you win some. Other methods I have tried on wheat pennies but no longer recommend are soaking them in the vinegar solution. Why does dish soap clean pennies?
