Slabline — the decision engine
Tells you what to do with it — what it would grade at each company, whether grading pays off, what you’d actually recover, and what’s at risk in one 0–1000 Score.
Questions only Slabline answers
What a tracker can’t tell you
What will it grade — and where?
PSA · BGS · SGC · CGC judge differently. See the grade each is likely to give from the card’s own centering, corners, edges and surface — and which one nets the most at that grade.
Should I grade it?
Real gem-rate odds × the value ladder − fees = your expected grading profit, in actual dollars.
What would I really get?
Market value vs. a dealer’s quick-sale offer — the liquidity gap, and why insuring at market matters.
What should I grade next?
Your raw cards ranked by expected profit — grade the ones that pay off first.
Every answer is built from real comparable sales, gem rate & population, and dealer spreads — across PSA, BGS, SGC & CGC. No other tool puts them together.
