Still up in the air on the best way to do this but I am learning. I have coins soaking in mineral oil in plastic cups that look better everytime I check them. Verdigone for stubborn verdigris on AU or lower copper coins. Rose thorns for dirt, grime removal. Not a fan of dipping unless the coins is practically black. Acetone for PVC which I personally have never owned a coin with such damage. Albums and paper flips or Taco Bell napkins to retone scratched coins- I use these methods and have no problem whatsoever- accelerated nature. MS 70- have done but not on any valueable coin. I will turn RB coins Blue, violet colors. I consider it AT, but still very pretty at times. I won&#039;t use on any valueable coin. Heating a coin- totally lame and damaging to the integrity. Never alter flow lines- a very important principle IMHO. I am the most in favor of mineral oil on non-PL copper coins. Silver coins would only use acetone if I suspected fingerprint issues.[/QUOTE]</p><p><br /></p>
