Is This Coin Consider Toned.

I do dislike that toning. I would pass regardless.

I"m no fan of toning in general, but I wouldn't say this is toned. It IS most definitely a product of poor storage. My Grandma'd come runnin' with a rag and tarnish remover...

Yes, it's toned.
It's just not "rainbow toning".
The toning is the common "shades of gray".

AU-58 is a GREAT grade.
That means it would have been an MS-63 or -64 if it weren't for a slight rub somewhere.
But it has the typical weak strike that plagued many of the 1940's WLH's. To me THAT would be the negative that would stop me from buying it.

An extremely common coin in a very common grade.

Toning does not appear the same on some series as on others, depending on how they were stored.

For example, finding a pretty natural toning on a Morgan dollar is pretty easy. Finding that same type of toning on a Walker half is virtually impossible.

The only "pretty" toning you are likely to find on a Walker is a golden hue. This gray drab discoloration you show here is much more common and detracts from the value (but not the technical grade).
