The result is that you remove all the crust and the dust but also part of the coin itself. More, as the patina is not a deposit but the result of a chemical reaction between the coin and its environment, if you remove it, you remove part of the metal. And some details of the engraving can be lost forever. </p><p><br /></p><p>Cucumbor</p><p>PS : I hope my pinguin english is understandable[/QUOTE]</p><p><br /></p>
