@chronos.
Thank you for bringing many interesting coins to the Forum (like this one) that we don't see very often.
I agree with coinfrog that your example is not as sharp as the PCGS graded one.
I think the KatzAUction example is pretty close to yours (maybe yours is even a bit nicer, at least to my eye), and I think the listed grade of "UNC" is a bit exaggerated, though for a roughly struck coin like this, I agree with coinfrog that assigning a grade is challenging.
