On your advice ttkoo ,i got some acetone from bunnings, how do I use it? Thanks
Put the coin in a glass jar with a screw top lid.
Add enough acetone to just cover the coin and re-lid.
Let the coin soak for a bit maybe a hour. Then remove the coin. Hopefully the discolouration has dissolved completely. If not you could continue the soak. If it is stubborn you can carefully try a q-tip bud dipped in acetone and gently try to dab the colour away. If it has already attacked the surface and etched into the coin, then all hope is lost. It doesn't hurt to give a final rinse in fresh acetone at the end.
CAUTION: The acetone is pretty volatile, do it in a well ventilated area or outside, away from sparks etc.
And is that coin clipped as well?
