One of electrolysis uses is purifying metals. Coins are metals, thus can be purified by electrolysis

Steps

  1. Gather the things that are needed. These are listed under "Things You'll Need".
  2. Connect four AA batteries in series to form a 6-volt DC power source.
  3. One alligator clip will be positive (anode) and the other will be negative (cathode). Test it by putting the coin on one clip. If it bubbles, put it on the other clip (the anode).
  4. Clip the nail onto the other clip (the cathode).
  5. Hold the two alligator clips in the water.
  6. The water should get dirty.
  7. After few minutes, disconnect the batteries.
  8. Unclip the nail and coin.
  9. Pour off the water.
  10. Deactivate the coin by rubbing it with water gently.
  11. Wipe the coin dry lightly with a piece of tissue paper.
  12. Finished.

Tips

  • If the coin you tested with turns out better, use it on other coins.
  • If it does not, do not use it (on collectible coins).
  • Go to an electronics store to find alligator clips such as http://www.radioshack.com/product/index.jsp?productId=2062237&CAWELAID=107591277.

Warnings

  • Do not use copper; it will stick to the coin.
  • Do not use stainless steel as it will create toxic chromates.
  • Do not get charged by the battery.
  • Don't do this if the old coins have ANY potential value, as this will decrease their value significantly. Any potentially valuable coins should not even be handled with your bare hands. Don gloves and put them in a plastic coin envelopes and get them appraised. The same goes for all antiques -don't clean, paint or polish anything that may have value before getting them appraised.

Things You'll Need

  • 2 alligator clips
  • a coin (to test with)
  • 4 AA batteries
  • salt or baking soda
  • water
  • container
  • something to dry the coin with
