I have a couple PCGS MS62 somewhat better date $20 Liberty gold coins.  I was trying to get input on the best solution to get the surfaces free of the undesirable substance.  PCGS guarantees are running upwards of 3 months; NGC has their $50 conservation/grading option on these.  And then I could just immerse them in a bath of acetone or xylene, no negatives on that but that I might not free the surfaces of the substance. I sure wish that submitters would use acetone more often before submitting as stains and unwanted dirt, etc. are aesthetic problems.
