If a coin's grade is a matter of opinion (and is there anyone who disagrees with that assessment) what's the point of all these "Guess the grade" postings?
When I give my opinion of a coin's grade, I am doing exactly that, not guessing at some immutably fixed "accurate" grade!
If the question is really "Guess what grade TPG X assigned this coin?" why not ask it that way?
If the question is really "What is the absolutely correct grade for this coin?", then it's a nonsensical question, undeserving of an answer.
Anyhow, that's what I'm .
