Altered Color?

Coins with "altered color" will generally have two major issues when it comes to conservation. First, just as coins with "artificial toning," the color has been added or changed often in an attempt to hide a surface problem such as an improper cleaning, environmental damage, or a simple contact mark. Changing the color will make these further problems more apparent. Secondly, "altered color" is usually referring to a copper coin. Color on copper coins is fragile which is why those red copper coins are so desired. Once the color has been altered even if we would be able to change it further the coin will still not look natural and will typically be not stable making the coin a poor candidate for conservation. In short, conservation can likely not fix "altered color."
