Is coconut oil good for copper coins, this is the same oil which people apply on hair.

Never tried it. Read the label. In general, fat is fine for copper, acid is not, but traces of acid don't matter all that much.

Tried to fine some scientific studies on that matter. There are quite some studies on its effect on steel. Not very much on its effect on copper, bronze and silver. However, while there is not much evidence of positive effects, there also is not much to be found on possible negative effects. So best advice might be just to try on cheap coins you already gave up on anyhow.

Most small dealers and collectors habitually leave copper coins with encrustations or mud in coconut oil for a long time (if required). Seems it has an almost similar effect as Olive oil on coins. It removes the grime, dirt, dust and some greens but leaves the coins almost undamaged.

PS: I personally do not use it - but I also do not use Olive Oil. I use the Soda mix which I find has a better result.

Look up the posts started by Bruce, our Moderator and expert on coin cleaning on this very board. I am grateful to him for having shared his secrets and knowledge on cleaning coins. They have been very helpful and I have benefited immensely from following his advice.
