Some
TPG give out 70s, but that just means to me that we need to highly suspect all their lower grades (is a MS-65 really an MS-63, etc.)
For business strikes, ICCS has a few MS-68. And I don't think they've ever given anything a 69 (even for NBU/PL/SP/PF)
69s/70s are given like candy by some
TPG. e.g. silver Maple Leaf bullion (SML) (gimme a break)
