Everyone who is curious about numismatics or is a professional collector himself asks this question.

Sometimes it happens that we find an old dusk coin somewhere in the attic or in a box with the useless stuff kept in the mezzanine for years.

And now what?! It is so dark, patined with dust and grime, that it is nearly impossible to identify it!

We bet most of you would say that one has to clean coins, nevertheless, everything is not so easy.

Cleaning coins, especially those that might be valuable for collecting, is a tricky thing. Aged metal money tends to form a patina, that dusk layer of tarnish that shows the item’s age and proves its value.

Professional collectors appreciate that touch of antiquity, that is why they normally leave the metal money as it is, dull and uncleaned. If patina is washed away, it can even reduce the coin’s price!

Nobody would like to cause damage to some precious and rare two hundred years old penny, right? Especially if it will cut its price twice as lower. At that point, remember that not all the aged metal money must be cleaned!

Now, let’s see what can be done to the metal money that is allowed to be cleaned

  • Wash your hands  
  • Bathe the metal rounds in warm soapy water

The way we use to clean old coins to keep them valuable for collections is slightly different from what was described above.

  • Smear the pieces of money with vaseline working with a cotton swab.
  • Carefully dab the shiners with a lint-free fabric to free from the vaseline layer. Like this, all the dirt will be deleted safely.
  • Immerse the metal money into the 100% acetone for five seconds and rinse with distilled water instantly. It is crucial to do it immediately since acetone will give the shiners brownish shade which will decrease their price.
  • Don’t wipe the metal money!

For better maintenance, keep the valuable metal money in plastic holders that are air-tight to protect the coinage from any external impact.

To make coinage even shinier, there is a safe way that won’t damage the precious metal rounds!

Remember though that rubbing or any other similar sort of polishing is unsuitable, especially for valuable items, since it will damage the surface of the shiner and it will lose the value.

For safer treatment:

  • Take a tank deep enough to put a coin inside
  • Pour white vinegar (no more than 5% or acidic acid) over to cover the coin
  • Add one big spoon of pure baking soda and wait for 10 min. If necessary, repeat the procedure until the coin is shiny again
  • For extremely dirty items, try to gently rub them with the fingers covered with baking soda
  • Then rinse the shiner under a cold tap

And remember: don’t do this unless you’re absolutely sure that the coins are OK to clean and they won’t lose the value.
