I only have a rough idea about grades - been studying the discipline for three years so nowhere near expert status. The guy I send my coins to sends me a report with his anticipated results which has a variable success rate with no discernible bias one way or the other i.e. sometimes he gets it right, sometimes he over-grades and sometimes he under-grades. The main thing is he takes care of nearly all the hassles.
