Effective sometime mid-2012. My point was that prior to this, half grades 70, 86 and 92 already existed so to receive a bump on review on SGC 60, 84 or 88 would mean SGC recognizing a mistake which would be rare.
Receiving a bump on review for lower graded cards would be more likely given that they may have been graded before half grades existed at those levels. You can estimate when SGC cards were graded because the cert numbers are chronological not random like PSA.


NEW SGC HALF GRADES
Effective immediately, four new half grades will be available as part of the grading scale. The new grades are as follows:
SGC 35 — 2.5 GOOD+
SGC 45 — 3.5 VG+
SGC 55 — 4.5 VG/EX+
SGC 82 — 6.5 EX/NM+
For years, collectors have been asking for more options at the lower end of the scale where condition can vary greatly. These new half grades will serve to reward cards that are high-end for their grade with special attention paid to eye appeal. All cards submitted for grading will be eligible for half grades—there is no special process. Cards that are already graded by SGC may be submitted for review under any of the applicable grading fee tiers.
These grades are being added to round out the options available when it comes to assessing trading cards. They are not being added to complicate things for collectors. As such, the labels will remain the same so that consistency within a collection can be maintained and the 100 point scale will be preserved to avoid difficulties with the registry, the population reports, and other established areas.
