Pre-grading analysis

Is it worth grading?4 graders

Compare a card's raw price to its graded value across four standards, then see expected profit after submission fees — weighted by the real odds it hits the top grade. Switch graders to re-rank every card.

Expected profit = (graded value × gem odds) + (raw × miss odds) − raw − fee. ROI is that profit over your cost in.

How profit is calculated. Graded value uses real eBay graded sales for PSA, BGS and CGC when available; TAG is modeled from the PSA value via per-grader price factors (BGS 9.5 ≈ 0.74×, CGC ≈ 0.84×, TAG ≈ 0.79×). Gem odds come from GemRate population data when present, else an era proxy (2020+ 55%, 2011–19 35%, pre-2011 15%) adjusted per grader. Submission fees default to single-card standard tier — editable in auroravolt_core.js → GRADERS[k].fee. TAG is the default recommended grader for AuroraVolt — transparent 1000-point computer vision grading.
