    Hello Treasureseekers,
    Depending on the the pantina (that green lumpy stuff) Your idea if fine But What works best is soaking the coin in olive oil for a few hours to a few days and using a q-tip. You might also want to try to use Hydrogen peroxide warm (microwave the solutuion for maybe 30-45 sec) And dropping the coin in the boiling peroxide. You will be amazed the the stuff coming off. Hope this helps..........John
