Your image makes the coin look dipped out and dead. The PCGS image shows the coin to have really nice luster.
Regardless of what the TPG said, I still say AU details because of all the scratches. Especially the one that runs from the ear all the way down and across the neck.
I dont think you understand the new grading standards for TPG This quarter graded G4 with PCGS, They disregarded the cleaning, rim damage, scratch, and gouge.
That's really a shame because that coin is clearly a problem coin for several reasons. This is why collectors need to educate themselves...because TPGs don't always get it right. This coin should not have been graded.
On the contrary, I understand them all to well. If a coin is a scarce date/mint, let alone actually rare, has a well known pedigree, or is more valuable that most, then the coin gets treated with leniency and is usually over-graded, or graded when it not worthy of being graded at all. And as long as you have been around this forum you should know that when I post my estimate of grade for any coin, I am not posting what I think the TPG said. I am posting my own personal opinion of what the coin should be graded, or not, as the case may be. That dime is a problem coin, plain and simple.
