MLB Breakout Rookie Cards (Hold), filed under base and rookie cards. Scored on four axes, because a type that gains value but can't be sold quickly is a different proposition from one you can move in a weekend.
Both of the upside numbers are strong here — appreciation 80, liquidity 85. That pairing is rare enough to be the reason this entry exists, and rare enough that the price normally reflects it.
Accessibility of 60 means you'll pay somewhat over the sensible number but not absurdly so. Worth watching, because this score moves faster than any of the other three.
Set against the 7 base and rookie card types scored here, its appreciation of 80 ranks 3rd of 7, liquidity 85 ranks 5th, accessibility 60 ranks 4th, and risk 40 is the 5th-lowest. The closest thing to it on the numbers is NFL Draft Rookie Cards (Hold), which scores 75 and 88 on the same two axes — if you're weighing one against the other, the difference is in the reasoning rather than the scores.
The window is about six months. Long enough that one bad month doesn't settle it, short enough that you're betting on a specific stretch rather than a career. Six-month positions are where people most often forget they set a deadline.
A risk score of 40 means ordinary risk — the failure modes are the boring ones, which is also why they're easy to talk yourself out of worrying about.
You can realistically find MLB Breakout Rookie Cards (Hold) at the card aisle at Walmart or Target, a local card shop, a card show and online.
The big-box card aisle is in play here, which mostly matters because it is the one place you can pay the sticker price instead of someone's asking price. Stock is erratic and restocks are usually early in the week.
A card show is worth the trip for this because you are buying a specific card rather than a sealed product: you can compare several copies side by side, check the centring and corners yourself, and negotiate — none of which a listing photo lets you do.
Every entry gets four separate scores instead of one grade, because a single grade hides the thing you needed. Full explanation in the guide: what Kabooms, Downtowns and Color Blasts are worth.
