NEVER CLEAN A COIN. CLEANING RUINS VALUE.
Note the orange tone of the coin in the picture. When copper coins are cleaned with harsh chemicals or polish, they inevitably take on an orange color. The color is bright immediately after the cleaning and gets dull as time goes on. But it never goes away.
