86 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
30 cards of his are listed and nothing comparable has verifiably sold, so we will not tell you whether the asks are fair.
Closest of his is 2025 Bowman Chrome 1st Sean Keys… at $19.99. Needs a $10 drop.
Our take
Strong prospect, untested market.
Sean Keys scores 86 out of 100 (#25 of the 7,922 we score), and the case rests on one thing: young for the level — +3.0y vs his level at Triple-A — younger than 95% of the players there.
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: corner-only profile — dH carries no defensive fallback — if the bat does not play, there is no version of this that works.
The signal
Young for the level
+3.0y vs his level at Triple-A — younger than 95% of the players there.
Speed: below average
3 SB per 600 PA — stolen bases per full season of plate appearances
Power: plus-plus
.325 ISO — isolated power — slugging minus batting average, so hits that go for extra bases Better than 95% at his level.
The case is strengthening
Baseball momentum 83/100 — ahead of the thesis. Read from his baseball alone — never from what his cards did.
Moved up and held it
High-A to Triple-A.
Bat-first profile
DH — there is no defensive value to fall back on, so the bat has to play.
Why now
No catalyst right now — no promotion, no logged step change, and no measurable move in his card prices. This is a valuation-driven watch rather than a timing one.
What could go wrong
Corner-only profile
DH carries no defensive fallback — if the bat does not play, there is no version of this that works.
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.
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 — no 1st Bowman vehicle observed for this player. 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.
No good entry today
The closest to fair is 2025 Bowman Sean Keys Chrome Auto Autograph 1st Prospect #CPA-SK Blue Jays at $20.98, 68% over the $6–17.99 that copies of it have confirmed sold in. Nothing of his is currently below its own sold band.
That card at or under $6 delivered would be at the bottom of what it has actually sold for.

What he is good at
skills overall 56 / 80
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.

years younger than the median player at his level — positive is young for the level
The overall figure averages the 4 skill rows only. The box-score row and the age row are shown but deliberately left out of it — one is the result those skills produced, and the other is not a skill at all.
The argument
skills at the 68th percentile of the cohort, production at the 94th — his results run further ahead of his tools than 87% of the players he is measured against.
The stat line is doing the selling and the skills underneath it are not carrying it. Pay for the line and you are paying for the part that does not repeat.
How this is read: his skills average 68 and his production sits at 94, a gap of -26. That gap on its own means little — an average of several percentiles always sits nearer the middle than a single one — so it is ranked against the same figure computed the same way for the 726 players at his level we hold a full profile for, where it lands at the 13th percentile.
Will he get there?
Strong chance 8.4 / 10
- already at Triple-A
- hitting well — 1.045 OPS in 198 PA (not ranked against his level)
- form is climbing
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 100% of what it wants to know.

Hitting better than last season even though the pitching got harder — .773 to 1.045 after moving up to Triple-A. That is the shape of a breakout.

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 missing1 thing 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 sold price in 90 days — add one and the whole price side fills in.
Worth reading for this player
- Parallel scarcity calculator — numbered parallels of his cards are in play, and print run drives the premium
- 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
