@Insider What makes you think this could be as low as AU58? Well even a details coin? At this point the thread has gone in quite a different direction than I wanted. There really is only one reason that this coin graded lower than it should have. The coin has enough luster and minor contact to be considered within the 66 grade, it is only missing the one trait that the majority of 38D's had and that is a full strike. I am not sure though if this is from a weak strike or some debris on the die (die fill), because all the other features on the coin look to be well struck.
Easy. In the images there is a change of color on the cheek and an arc in the hair. These are places where the first trace of friction show on these coins. At this time, most dealers ignore that strict interpretation of MS. So... for numismatists who are conservative about the choices they make, AU-58. Next, I'll guarantee some folks would consider this AT = "details." No worry, the #2 TPGS has considered its color OK or "market acceptable." Next, the strike is not full. That no longer matters to some because one requirement for a 65 grade (full strike) went out the window at least a decade ago possibly because coins from some mints rarely come with a strong strike. The eye appeal of your coin is a matter of personal taste. Unfortunately, there was no intelligent way to comment on the coin w/o knowing the assigned grade. Suppose it was in a MS-67 slab. What keeps it form grading higher? Bottom line. You got a coin you like a lot at a very good price!
I think I see what you are referring to in the hair. That is why I said weak strike, What it actually looks like in hand is a slight strike thru. I see no evidence of circulation. One of the only reasons I bought it was for the RPM-009. I am trying to rebuild my RPM and OMM collection. Then got it home and the mm is tilted and not and RPM. If it was the D/D I would have paid about half of the value.
