barrysloateGem Mint + is your proverbial PSA 11 or SGC 105.
There is an oddity to SGC's grading system, and it makes no sense. From 10 to 80 it increases in standard 10 point increments. Then, it goes to 84, 86, 88, 92, 96, and 98. Sometimes it jumps by 4 points, then by 2, then back to 4. Why?
One thing I might change is to leave SGC 10 as poor, and 20 as fair, but add an intermediate 15 grade. 10 would be for cards that had holes or corners missing; while 15 would be for heavily worn cards that were entirely intact. I don't know how much that would matter, but it would take into account the idea that there are different levels of beaters.
