It is best to actually see a coin in order to give an accurate evaluation on any potential conservation. Based on coins that look similar, we likely could remove the spotty toning on this Dime. In order to determine for certain, however, we would have to see the coin in person. Since the coin is already graded it will also be evaluated to determine if the currently stated grade will at least be maintained through the conservation process. If there is a perceived risk that the grade may not maintain, the coin will not be conserved.
