Our take

Solid prospect, untested market.

Gavin Kilen scores 67 out of 100 (#419 of the 7,922 we score), and the case rests on one thing: young for the level — +2.0y vs his level at Double-A — younger than 91% of the players there.

His core Bowman card has been selling at $20–33 off 1 confirmed sale.

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: 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.

The signal

  • Young for the level

    +2.0y vs his level at Double-A — younger than 91% of the players there.

  • Speed: below average

    4 SB per 600 PA — stolen bases per full season of plate appearances

  • Contact: plus-plus

    14.1% K — strikeout rate, inverted — lower means more bat-to-ball Better than 94% at his level.

  • Moved up and held it

    Low-A to Double-A, though the prior season is a thin sample.

  • Premium position

    SS — the bat does not have to carry the whole profile.

  • Power: above average

    .159 ISO — isolated power — slugging minus batting average, so hits that go for extra bases 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

  • 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.

  • Benchmark not checklist-verified

    His core card was identified from how raw base 1st bowman draft chrome auto sellers describe it, not from a checklist. The identity is likely, not established.

What the hobby pays for him

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.

2025 Bowman Draft 1st Auto CPA-GK

Raw base 1st Bowman Draft Chrome Auto

The draft-class equivalent of the canonical auto — same card kind, other product line. Identified from 2 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 2025 Bowman Draft Chrome Prospect Gavin Kilen #CPA-GK Auto k0r at $74.24, 271% over the $20–26 that copies of it have confirmed sold in. Nothing of his is currently below its own sold band.

That card at or under $20 delivered would be at the bottom of what it has actually sold for.

  • Needs a $16 drop

The parallel ladder3 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.

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 atSkills 52 on the 20–80 scale, against 496 hitters at Double-A

What he is good at

skills overall 52 / 80

On the 20–80 scale every scouting report uses: 50 is average, and every 10 points is one standard deviation. Measured against 496 hitters at Double-A — measured against real players at the same level right now — not a scout's projection of what he becomes.

    63

    plus · better than 91% at his level · context, not a skill

    +2.0y 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 53th percentile of the cohort, production at the 79th — his results run further ahead of his tools than 88% 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 53 and his production sits at 79, 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 496 players at his level we hold a full profile for, where it lands at the 12th percentile.

Will he get there?

Real chance 6.2 / 10

  • already at Double-A
  • hitting well — 0.823 OPS in 135 PA (not ranked against his level)

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.

Is this player getting better?

Hitting better than last season even though the pitching got harder — .561 to .823 after moving up to Double-A. That is the shape of a breakout — but last season was a small sample, so go easy on it.

Moved up from Low-A to Double-A — the pitching is harder this year.

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.
