This would be reasoning behind determining the grade,below is 2 examples,1 is a VF35PCGS the other will be a AU58PCGS if you look at key points,it will help in determining the grade for this coin.and you will see why I would net it at the VF35 If you look at the detail,mainly on the left side of the coin,you will see how the dirt has slowly decomposed the coin,it left some fairly better details on the lower right side,where the coin was better protected.the flatness of the stars,is another key area.to the left side,they are flat,and to the right bottom they are slightly detailed.the overall strike of the coin was a good strike.it just over time has lost detail from "decomposition" in "total mass",plus it would never get an "actual" grade.only a "net" grade or "details" grade.Being from the ground,it has lost it "numismatic" value as a mint state coin.So with a net of XF40 from being buried,down to a VF35 with active corrosion.I also dont think there is much more that can be done to the coin,to preserve it,by removing any more material "patina" of the copper,will most likely result in heavy pitting underneath.and then the coin will just be another junker.. I dont ever believe it would be net graded to a MS coin,even in AU,there still has to be luster remaining. Numismatic grading is based on normal displays of circulation,or uncirculation.copper is a metal that "sucks" the chemicals towards it.
Agreed. I have trouble separating the modern grades from the traditional ones and sometimes overcompensate for the Grade Inflation.
Rotation Hi Scott I have one also mine is an 1833:high5: Im about to send mine off to have it graded Ive been told that on these errors that the rotation must be at least 37 degrees to qualify as mint error yours appears to have more rotation than mine does dont know about the green tint on yours hopefully not pvc holder tint
