<p>[QUOTE=&quot;desertgem, post: 3116920, member: 15199&quot;]No, I haven&#039;t done cleaned coins. As far as I know, most graders use a 5X-7X magnifier to grade coins ( maybe a little more for varieties or such~ although I do not know. Actually most cleaning may&nbsp; be done with minor depth scratches. however they disturb the reflection of light enough to be detected with little or no magnification. Cleaning is most noticeable on proofs or other similar coins. Microscopic corrosion areas can also disturb the lustre Or&nbsp; alter it in such a way we perceive it as Toning as they are both chemically active processes.[/QUOTE]</p><p><br /></p>
