My suggestion: keep them in olive oil for a month. This should solve the upper layer of green. Wash with soap in lukewarm water to remove the oil and wipe firmly with your thumb. Dry well. If you are happy, fine. If not, report back here.

Thanks for the advice!

These coins have been olive oil for around 3 weeks now along with a few other coppers/brass and silvers.
My questions:
1. Is it fine to put all those metal coins in together?
2. I think there is a black patina over a few of the coins. Any specific reason for the same?
3. Would be fine to rub them with a fine toothbrush to get the rid of the excess?

Thank you in advance!
