36 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
42 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 2026 Bowman Chrome Seojun Moon Auto 1st… at $14.49. Player not there yet.
Our take
Fringe prospect, untested market.
Seojun Moon scores 36 out of 100 (#3836 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; only 19.0 — years of runway.
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
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; only 19.0 — years of runway.
Why now
Listed at your price — $65.00
target is $85.00
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.
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.

What the same money buys today
Nothing of his is worth buying right now. These live cards from other players are the ones we rate as a buy or a watch at the same budget — not a view on Seojun Moon, just what the money can do today.

The parallel ladder7 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 1087 hitters at Rookie — 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?
51
average · better than 54% at his level · context, not a skill
0.0y vs his level
years younger than the median player at his level — positive is young for the level
Will he get there?
Long shot 4.1 / 10
- nothing stands out either way
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 68% of what it wants to know — missing readiness, 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.
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
