I've never really thought to much about grades. So many different grading services with slightly different opinions. Since I put almost all my coins in Albums, their grades mean little to me. I naturally want the best coins in my albums but since when and if I buy one in a slab with a grade on it, the slab goes into the garbage and the coin into my Albums. For example with my #1 set of
Mercury dimes, all musts have FSB's. So if MS-60 or -70, makes no difference. If I like it and it has FSB, into the album.
