Yes, I had a VF British 1915 Half Crown once (maybe even VF was pushing it, it was perhaps even AVF). It was slabbed and graded by I can't remember who, but it was one of the big companies, as AU55! It had loads of wear on both sides. I'm sure they look at them through powerful magnifiers etc, and I'm sure they mean well, but at the end of the day, they too are human. I had to break the coin out. And a respected human coin dealer who specialises in the coin you are showing him, would probably let you know what grade he thinks it is for free.
