52 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
11 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 2024 Bowman Chrome Walker Martin 1st Auto…. Waiting on sales.
Our take
Fringe prospect, untested market.
Walker Martin scores 52 out of 100 (#1690 of the 7,922 we score), and the case rests on one thing: young for the level — +1.0y vs his level at High-A — younger than 74% 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: swing-and-miss — contact grades 41 on the 20–80 scale (33.1% K). strikeout rate, inverted — lower means more bat-to-ball
The signal
Young for the level
+1.0y vs his level at High-A — younger than 74% of the players there.
Contact: well below
33.1% K — strikeout rate, inverted — lower means more bat-to-ball
Power: above average
.185 ISO — isolated power — slugging minus batting average, so hits that go for extra bases Better than 75% at his level.
Moved up and held it
Low-A to High-A.
Premium position
SS — the bat does not have to carry the whole profile.
Speed: above average
24 SB per 600 PA — stolen bases per full season of plate appearances Better than 62% at his level.
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
Swing-and-miss
Contact grades 41 on the 20–80 scale (33.1% K). strikeout rate, inverted — lower means more bat-to-ball
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 — 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.
No good entry today
The closest to fair is 2024 Bowman Chrome Walker Martin Auto 1st Bowman Sapphire Giants #BSPA-WM at $18.74, 212% over the $6 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 would make this a buy
- Waiting on sales
- Player not there yet
What is for sale right now
11 cards of his are listed, 1 held back on condition or a broken price · 0 of the 10 we can judge clear the investment bar. These are the 6 worth looking at, best first; the other 4 are under "The whole live market".

The parallel ladder2 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.

On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 492 hitters at High-A — measured against real players at the same level right now — not a scout's projection of what he becomes.

+1.0y vs his level
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 48th percentile of the cohort, production at the 55th — the gap between the two is ordinary for this level.
Nothing to arbitrage here: he is producing about what his skills say he should. Judge the card on price and the player on the grades.
How this is read: his skills average 48 and his production sits at 55, a gap of -7. 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 492 players at his level we hold a full profile for, where it lands at the 38th percentile.
Will he get there?

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.

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 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
- What a modeled fair value means — at least one value on this page was modeled rather than taken from a sale
- 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
