After a lot of experimenting and reading how other people try cleaning coppers, I have come up with my own method which has good results. I have used it on Large Cents, Indians and Wheats. Does not fix corrosion, but if the date is there, you will get it. It also generally keeps the coins patina.
Materials:
1) Small Bowl
2) Toothbrush (one you DON'T plan on using again)
3) Soda ( I prefer a lemon Lime so that you can observe the coin and see the progress)(UPDATE: SIERRA MIST works best)
4) Olive Oil
Method:
1) Clean the coin in warm soapy water and scrub with toothbrush, then dry coin off
2) Place coin in small bowl and pour the soda in it. You will notice bubbbles forming on the coin. Let set for about 4 hours. Remove coin, give a scubbing with the toothbrush. This process will need to be repeated depending oncondition of the coin and will also have to be repeated for the other side of the coin. Do not forget about the coin...you have heard that myth about soda dissolving a penny....kinda true, but not completely. So long as you do not leave it in for too long and keep tabs on it, you will be ok.....Disclaimer.....I have no liability and guarantee no success of your endevor (sorry attorney in me)
3) Remove coin and dry off after achiving desired result. It may not get off all corrosion.
4) You will notice that the coin feels dry, and may have a bit of a silvery look to it....that's ok, the generally come out of the ground pretty dry anyways, as the soil has sucked the oils out.
5) Clean and dry the bowl...or use another (my wife hates me dirtying too many things) place the coin in the bowl and pour olive oil in the bowl, just enough to cover it. Let it set for days. Every day or so pull the coin out and massage the oil into the coin. This restores the oils back into the coin. What gives coins their patina is the oils from peoples hands. Do this until you reach your desired look. I find that it varies from 2 days to a week.
