5 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
15 cards of his are listed and nothing comparable has verifiably sold, so we will not tell you whether the asks are fair.
Nobody has logged a completed sale for this card, so we can't say what it's worth.
Our take
Long-shot prospect, untested market.
Isaiah Campbell scores 5 out of 100 (#7041 of the 7,922 we score), and the case rests on one thing: what the hobby pays up for — SP sells at a discount at equal production; 29.0 is old for a prospect card.
Nothing of his has verifiably sold in 90 days and there is no benchmark price, so we will not tell you what his cards are worth.
Cards of his are listed and none of them can be priced against a confirmed sale, so any judgment about value today would be a guess dressed as a number.
The thing most likely to be wrong here: no professional sample — we hold no season line for him, so every player-side reading on this page is missing its main input.
The signal
Old for the level
-3.0y vs his level at Triple-A — younger than only 17% of the players there.
The case is fading
Baseball momentum 0/100 — the on-field case is fading. Read from his baseball alone — never from what his cards did.
What the hobby pays up for
SP sells at a discount at equal production; 29.0 is old for a prospect card.
Why now
3 new copies listed this week
Fresh supply on this exact card. More choice, and more downward pressure.
What could go wrong
No professional sample
We hold no season line for him, so every player-side reading on this page is missing its main input.
Age for the level
-3.0y vs his level at Triple-A puts him younger than only 17% of the cohort. The clock is a real cost on a prospect card.
Nothing has sold
No confirmed sale of any card of his in 90 days, so nothing on this page can tell you what a fair price is.
Modeled value only
The fair values shown for his live cards are arithmetic from related evidence, not confirmed sales of the exact card.
What the hobby pays for him
A benchmark is the one standardized card we track a player's market on, so every player's price means the same thing.
Benchmark not yet established — candidates seen, none corroborated by enough sellers. Until one exists, only his individual listings can be judged.
The card that matters
A card-quality answer, not a price one. It does not change when a seller changes their mind.
Canonical card not established — We have not assigned him a benchmark card yet, so there is no canonical answer to give. Until one exists, only his individual listings can be judged.
Best value right now
Where the money would go today, which is frequently a lesser card than the one above — or nowhere.
Insufficient market evidence
No live ask and no confirmed sale on any version of his cards, so there is nothing here to call good or bad value.
What would make this a buy
- On his best-priced card: past the window.
- A promotion, or a stretch that lifts the season line, would move the player side of this.
What is for sale right now
15 cards of his are listed · 0 of the 15 we can judge clear the investment bar. These are the 6 worth looking at, best first; the other 9 are under "The whole live market".

The parallel ladder4 versions of his cards in raw autos, each priced off its own confirmed sales
Every version of his cards we can see, base to 1/1. Each rung is priced off its own confirmed sales — a rung nothing has verifiably sold at shows no value rather than borrowing a neighbour's.
Showing Raw autos.
NO CLEAR SWEET SPOT
No rung of his has a confirmed sale behind it, so there is no price to compare any step against.

What he is good atno percentiles against his level yet
What he is good at
On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 728 hitters at Triple-A — measured against real players at the same level right now — not a scout's projection of what he becomes.

This is an ordering score, not a percentage. We hold no outcome data and have run no backtest, so “a 93% chance of reaching the majors” would be a number we made up and you then spent money on. Built on 86% of what it wants to know — missing production.
How he is playingno season line on file
We hold no season stat line for him. That happens when he has not played enough this year, or when the roster refresh has not reached his level.
What his cards have sold forno completed sales logged yet
Real completed sales only — nothing here is an estimate. These come from the scan: it asks eBay about listings it has already seen, and one that ends at a fixed price is recorded as a sale. That builds up over days. You can add one by hand below if you happen to know it, but you are not meant to be the price database.
No sales logged yet. We need at least two to draw a line, and about five spread over a month before the numbers mean much. Add sales you find using the button below.

What this page is missing3 things we do not hold for him
What this page is missing
Everything above is built from what we actually hold. These are the gaps, so you know which parts of the argument are thin rather than wondering why a panel is quiet.
- We do not have a season stat line — he may not have played enough yet.
- We do not have percentiles against his level — the roster refresh computes these.
- We do not have a sold price in 90 days — add one and the whole price side fills in.

- Best Offer calculator — at least one of his live listings accepts offers
- Certified vs aftermarket autographs — signed cards of his are listed, and the two kinds are not worth the same
- Parallels and print runs — his market includes numbered parallels, which are priced off the print run
