Heuristic screen built on the public research: age-relative-to-level is the master filter, then the sticky predictive metrics — contact quality (zone-contact & chase) and impact (hard-hit & 90th-pct EV) for hitters; K-BB% and velocity for pitchers. It ranks and tiers; it does not predict.

Watchlist

Player Age/Lvl Age vs Lvl Contact Impact Score Tier Read
Method note. A transparent decision-support heuristic inspired by KATOH/OOPSY-style public research — not a validated projection model. Pitcher velocity is essentially AAA-only in public data; don't over-penalize a low-level arm for a blank. Pair every score with scouting (injury, position retention, mechanics) — those aren't in the numbers.

Cost basis = purchase + grading + shipping (matters for taxes). P/L is vs. your current comp — always a recent sold comp from 130Point/Card Ladder, never an asking price. Holding period flags the collectibles tax treatment (long-term capped at 28%).

Tax note. Collectibles long-term gains (held >1yr) are capped at 28% but it's a cap — you pay your ordinary rate if lower. Short-term (≤1yr) = ordinary income. Keep these records; this isn't tax advice. Verify the current 1099-K threshold separately.
