<p>[QUOTE="GDJMSP, post: 12991, member: 112"]All good explanations - but in very simple terms : when the luster is intact on a coin (untoned) and you turn it in the light the color will appear to be almost white or very bright silver. A break in the luster will appear to be a dull grey.

A break in the luster will appear to be a dull grey. This indicates wear or at the very least - friction. Once you see this the first time - you'll be able to see it from across the room ;) It should be noted though that with some coins, particularly very old coins, these minor breaks in the luster will not prevent the coin from being graded as UNC.[/QUOTE]
