Our take

Fringe prospect, untested market.

Christian Knapczyk scores 38 out of 100 (#3693 of the 7,922 we score), and the case rests on one thing: moved up and held it — High-A to Double-A.

His core Bowman card has been selling at $2–4 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: thin comp evidence — 1 confirmed sale in 90 days. Treat any value here as a single data point, not a price.

The signal

  • Power: below average

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

  • OPS slipping

    .719 last season to .520 this one.

  • Power slipping

    .111 last season to .083 this one.

  • Moved up and held it

    High-A to Double-A.

  • Premium position

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

  • What the hobby pays up for

    SS is a position the hobby pays up for; 24.0 is old for a prospect card.

Why now

  • 3 new copies listed this week

    Fresh supply on this exact card. More choice, and more downward pressure.

What could go wrong

  • Thin comp evidence

    1 confirmed sale in 90 days. Treat any value here as a single data point, not a price.

  • 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 raw base 1st bowman chrome auto sellers describe it, not from a checklist. The identity is likely, not established.

What the hobby pays for him

Benchmark card: 2022 Bowman Chrome 1st Auto CDA-CKN — raw, base, unnumbered.

Described by 2 independent sellers — observed, not checklist-verified.

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.

2022 Bowman Chrome 1st Auto CDA-CKN

Raw base 1st Bowman Chrome Auto

The canonical prospect vehicle — every player who has one is compared on it. 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.

Insufficient market evidence

No live ask and no confirmed sale on any version of his cards, so there is nothing here to call good or bad value.

The parallel ladder4 versions of his cards in raw autos, each priced off its own confirmed sales

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 atSkills 46 on the 20–80 scale, against 496 hitters at Double-A

What he is good at

skills overall 46 / 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.

    53

    0.0y 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 36th percentile of the cohort, production at the 13th — his tools run further ahead of his results than 85% of the players he is measured against.

The market prices the stat line, and his is behind what he is doing. That is where a card is cheap for a reason that can change.

How this is read: his skills average 36 and his production sits at 13, a gap of +23. 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 85th percentile.

Will he get there?

Long shot 4.5 / 10

  • already at Double-A
  • old for Double-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 100% of what it wants to know.

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.
