I will do my best to describe what I have seen on some raw MS Morgan's in person. The couple have been ~MS63 in grade.
The coin has a nice, unbroken, cartwheel on it. However they don't quite have that frosty luster that a lot of others have. It is almost like a bit more shine than frost, if that makes sense.
This picture doesn't really show it, but this is one of the coins that I purchased that have that quality.

Is this something that can be common in the MS62/63 range or could it be the result of the coin being dipped?
