8 out of 100 — our all-round score from the season line, his tools against the level, and how young he is for it.
39 cards of his are listed and nothing comparable has verifiably sold, so we will not tell you whether the asks are fair.
We can't see what this costs all in, so there's nothing to judge yet.
Our take
Long-shot prospect, untested market.
JJ Goss scores 8 out of 100 (#7510 of the 7,942 we score), and the case rests on one thing: what the hobby pays up for — SP sells at a discount at equal production; 25.0 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: pitcher — injury risk is materially higher and the resale market is smaller, which is why the strategy caps what share of a book pitchers can take.
The signal
Stuff: well below
15.6% K — strikeout rate per batter faced — never per nine innings, which flatters a pitcher who allows more baserunners
K-BB% slipping
11.9% last season to 4.8% this one.
Strikeouts slipping
19.4% last season to 15.6% this one.
What the hobby pays up for
SP sells at a discount at equal production; 25.0 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
Pitcher
Injury risk is materially higher and the resale market is smaller, which is why the strategy caps what share of a book pitchers can take.
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.
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: 2019 Bowman Chrome 1st Auto — raw, base, unnumbered.
Described by 6 independent sellers — observed, not checklist-verified.
No price on this card yet
sales exist for this player, none on the benchmark card 6 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.
2019 Bowman Chrome 1st Auto
Raw base 1st Bowman Chrome Auto
The canonical prospect vehicle — every player who has one is compared on it. Identified from 6 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.
Insufficient market evidence
Nothing of his has confirmed sold, so there is no value to measure against. Among the asks alone, /150 at $5.49 costs 1.29× base, and print run alone suggests 1.50×, with no measured sales to check it against — best balance available. That is a comparison of sellers, not evidence of what these are worth, and it rests on the print-run assumption rather than measured premiums.
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
39 cards of his are listed, 1 held back on condition or a broken price · 0 of the 38 we can judge clear the investment bar. These are the 6 worth looking at, best first; the other 32 are under "The whole live market".

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 at
skills overall 44 / 80
On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 567 pitchers at Double-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 3 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 29th percentile of the cohort, run prevention at the 46th — his results run further ahead of his tools than 81% 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 29 and his run prevention sits at 46, a gap of -17. 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 566 players at his level we hold a full profile for, where it lands at the 19th percentile.
Will he get there?
Long shot 3.9 / 10
- already at Double-A
- old for Double-A
- pitcher — more of them break down before they arrive
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 76% of what it wants to know — missing production, form.

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
