Is it even possible to see luster on a coin this heavily toned?


You can clearly see luster at 9 and 3 O'Clock on the obverse. Light toning like this, luster can be slightly dimmed but still very clear.


Quote:
As Sel points out, toning is essentially very shallow corrosion. Wouldn't that dull the luster or occlude it entirely?


Luster completely disappears in the deep terminal stage of toning when the coin is visibly corroded. If the coin has hazy toning, the luster can be dimmed as well. But once dipped, the luster is revealed.

I like toned coins, but not these type and difficult to tell from just pictures, which is part of the reason why buyer entrust 3rd party graders help in determine its states. A similar coin I have from the one selling on ebay helps me determined the level of luster, and the brightness of luster that comes out on the surface itself.

Dull toning where the surface have a thin coating that hid the actual luster is something I avoid.

For my eyes, the toning DOES inhibit my ability to interpret field luster ... as a "toned coin guy", I love it. For the price due to the grade ? not a buyer.

Looks MS but can't grade a toned coin like that if not in hand.

Yes, there can be luster under toning.
