5 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
35 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 SEM ROBBERSE 2023 Bowman Chrome Purple…. Player not there yet.
Our take
Long-shot prospect, untested market.
Sem Robberse 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; 24.0 is old for a prospect card.
We have 1 confirmed sale of his cards in the last 90 days, but no standardized benchmark card yet, so the price side rests on whatever is listed rather than on one comparable series.
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 Low-A — younger than only 11% 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; 24.0 is old for a prospect card.
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
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 Low-A puts him younger than only 11% of the cohort. The clock is a real cost on a prospect card.
Thin comp evidence
1 confirmed sale in 90 days. Treat any value here as a single data point, not a price.
Benchmark not checklist-verified
His core card was identified from how sellers describe it, not from a checklist. The identity is likely, not established.
What the hobby pays for him
Benchmark card: 2023 Bowman Chrome 1st Auto CPA-SR — raw, base, unnumbered.
Described by 11 independent sellers — observed, not checklist-verified.
No price on this card yet
sales exist for this player, none on the benchmark card 17 copies are listed right now — asking prices are supply, never evidence of what it sells for.
This is his benchmark, not the value of any particular card in front of you — a /250 is a different market.
The card that matters
A card-quality answer, not a price one. It does not change when a seller changes their mind.
2023 Bowman Chrome 1st Auto CPA-SR
Raw base 1st Bowman Chrome Auto
The canonical prospect vehicle — every player who has one is compared on it. Identified from 11 independent sellers describing it — likely, not established.
A card is never the one to own because it is numbered. Scarcity is a modifier on a vehicle, not a vehicle — a /25 of a card nobody collects is a rarer version of nothing.
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 2023 Bowman Chrome Sem Robberse #CPA-SR 1st Auto Prospect Cardinals at $14.48, 811% over the $1.59 that copies of it have confirmed sold in. Nothing of his is currently below its own sold band.
That card at or under $1.59 delivered would be at the bottom of what it has actually sold for.
What would make this a buy

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 530 hitters at Low-A — measured against real players at the same level right now — not a scout's projection of what he becomes.
Contact
Can he hit it?
—
not measured for him yet
—
strikeout rate, inverted — lower means more bat-to-ball
Power
Can he hit it hard?
—
not measured for him yet
—
isolated power — slugging minus batting average, so hits that go for extra bases
Plate discipline
Does he pick his pitch?
—
not measured for him yet
—
walk rate — higher means he makes pitchers come to him
Speed
Can he run?
—
not measured for him yet
—
stolen bases per full season of plate appearances
Production
Is it showing up in the box score?
—
not measured for him yet
—
on-base plus slugging — the result, which carries the luck as well as the skill
Age for the level
Is he doing it young?

years younger than the median player at his level — positive is young for the level
Will he get there?

- old for Low-A
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 for1 logged sale
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.
Only 1 sale logged so far. 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 missing2 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.
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
