Coin and Paper Money Collecting/cents


how can I clean a cent with corrosion, etc. on it so I can read the date?

Hi Ralph,
Cleaning the coin will destroy all collector value.  I don't advise anyone to clean coins.

That said, if a copper coin is corroded (green), the old timer way is to put the coin in an air tight container with olive oil. Seal it up, and put it aside for a year or so.  I'm not a chemist, but I can tell you that for some reason it works and does little damage to the coin.

Good Luck!
