Things seem to get really tough at the upper end of grading. I've only done a handful of modern cards and those through SGC. I had a huge batch of 81 Topps, and picked what I thought were almost perfect examples of commons that had low populations in PSA 9 and 10. (SGC has almost no population on those at all) Didn't do all that bad, but didn't do all that good either. A couple 9s, mostly 8 or 8.5, The other modern stuff also got 8s.
I'd target a few likely ones, looking at the population. For the minis it's probably worth the chance on a few as part of a bigger submission. But they have to be really almost perfect.
