The Report Card is built by Bayley Coleman, a sports-card collector and flipper based in Fresno, California.
I buy raw cards, grade them, and sell the slabs. The whole game is one question, asked over and over: is this card worth buying at this price, and is it worth grading. Most tools answer a different question, what a card already sold for, and leave the decision to you. I wanted the decision itself, with the math shown and the uncertainty admitted.
So I built The Report Card. You enter the ask price, your own sold comps, and the pop report. It returns expected value, a max-buy price, and a grade-or-not read across PSA, SGC, BGS, and CGC, with an honest confidence range instead of a fake exact number. It informs the call. The call is yours.
Every public number I put out is sourced and dated. Every call I make with the engine is logged on the public track record, timestamped by the server before the outcome exists. Wins and losses both stay up. If the engine is wrong, you will see it. That record is the point.
I post the work on Instagram at @the.report.card, and write up the thinking in Field Notes. Questions or corrections are welcome.
