Slabwright guides. Submission prep for PSA, BGS, SGC and CGC.
Short, plain-English guides to the four graders Slabwright supports — PSA, BGS, SGC, and CGC. The hobbyist trip-ups on each intake form: bulk and tier rules, the $500 declared-value threshold, sub-grade math, re-holder / crossover mechanics, and how Slabwright maps your CSV onto the right column set for the grader you picked.
PSA submission prep
Pillar
The four things every first-time PSA bulk submitter trips on: 20-card cap, See Attached, declared value math, batch sizing, and how Slabwright solves each.
BGS submission prep
Pillar
The four BGS sub-grade categories — Centering, Corners, Edges, Surface — the weakest-link rule that determines the composite grade, BGS declared-value triggers across the six grading tiers, and how Slabwright's BGS schema export columns map to Beckett's submission form.
SGC submission prep
Pillar
SGC's 1–10 grading scale, raw vs. cross-over / reholder mechanics, the per-tier declared-value rules and the single-card $500 trigger, and how Slabwright's SGC schema export columns map onto the SGC submission form.
CGC submission prep
Pillar
CGC's four grading tiers — standard, express, walkthrough, bulk — the $500 walkthrough-tier declared-value rule, raw vs. re-grade / crossover on the 0.5-10 scale, and how Slabwright's twelve CGC schema columns map onto the submission form.
