We just launched. Comp coverage is still building, so some fair-value numbers are preliminary — here's how we handle that.

What we hold for him

Existence first, opinions after. These are counts of our own index, before any investment gate — and the last two say how much of it we have actually analysed.

These count OUR index, not eBay's. A number here going to zero means our scans hold nothing, never that nothing is for sale — which is what the searches further down are for.

No benchmark price yet. No 1st Bowman vehicle observed for this player. Asking prices are supply, never evidence of what a card sells for, so nothing on this page fills that gap with one.

The vehicles we prefer

Four rungs, in a fixed hierarchy — a position in a documented list, not a score. Each rung shows what our index holds and opens the same rung on eBay, whether we hold anything or not.

  1. Raw base 1st Bowman Chrome AutoCore vehicle #1 of 4 in Bowman hierarchy — the canonical prospect vehicle — every player who has one is compared on it.—none in our index
    eBay All of these on eBayNothing of his on this rung in our index — the search asks eBay directly.
  2. Raw base 1st Bowman Draft Chrome AutoCore vehicle #2 of 4 in Bowman hierarchy — the draft-class equivalent of the canonical auto — same card kind, other product line.—none in our index
    eBay All of these on eBayNothing of his on this rung in our index — the search asks eBay directly.
  3. Raw base 1st Bowman Chrome (non-auto)Core vehicle #3 of 4 in Bowman hierarchy — no certified 1st auto exists for this player — the non-auto 1st Chrome is the core card.—none in our index
    eBay All of these on eBayNothing of his on this rung in our index — the search asks eBay directly.
  4. Raw base 1st Bowman Draft Chrome (non-auto)Core vehicle #4 of 4 in Bowman hierarchy — documented fallback — neither an auto nor a flagship Chrome 1st is observed.—none in our index
    eBay All of these on eBayNothing of his on this rung in our index — the search asks eBay directly.
  5. Every search above carries Marcelo Mayer's name, the 1st Bowman framing and our standing exclusions (reprints, customs, digital, sticker autos, coins, breaks). eBay decides what it returns; we only ask.

Listings we have analysed

Our own rows, ranked by card fit, then identity confidence, then a measured value edge, then listing quality — price last. Each carries the action our gates reached for it, and each link re-checks the listing is still live on the way out.

The live eBay market

Everything above is what we hold. This is everything else.

These go straight to eBay, unanalysed. They run our targeted query for Marcelo Mayer — his 1st Bowman series, with our standing exclusions — but what comes back has passed none of our gates. No identity check, no condition read, no valuation, and no verdict of ours attaches to any of it. Treat it as the marketplace, not as a recommendation.

Completed sales are a different question from current inventory — what somebody paid, not what somebody wants. We price cards from our own stored sold comps; this link is for reading, and nothing behind it is fed back into a valuation.
