It&#039;s not reacting with something on the coin, it&#039;s reacting with the metal itself. You can take a freshly minted cent, that has nothing on its surface, and dip it in MS70 and the coin will turn a shade of blue or purple.</p><p><br /></p><p>And you can further prove this by rinsing the cent in xylene first, which will remove anything on that may be on the surface, and then dip it in MS70.
