Why prices differ
TCGplayer's figure is what sellers are asking on their marketplace, not what copies sold for — an asking price sits above a completed sale because it is the start of a negotiation, not the end of one. Our price comes from those same completed sales, adjusted to Near Mint — the median below mixes every condition together, and most copies that change hands are played rather than mint.

Compare graders, and the live market
The verdict above is PSA's — the grader the population report, the ROI table and the price ladder on this page all use. Trader prices all three graders against each other and adds what the asking market is doing right now.
- PSA, CGC and Beckett side by side — each on its own population and its own fees, with Beckett scored on the 9.5 its market actually pays for.
- Lightly and moderately played — the same expected return for a copy that cannot gem.
- Ask vs sold — what the live listings want, against what copies have really closed at.
- Momentum — the 30-day median against the 90-day, per grade.
- Where it sells higher — the Fanatics-versus-eBay premium, with the sale counts behind it.
- Population history — the weekly PSA census, so you can see how fast 10s are arriving before you post the card.
The odds
Alolan Marowak-GX is a Commoncard — a guaranteed slot in every pack, not a rarity gamble, so there's no pull-odds figure for it.
Estimates only. Pack odds come from CardTrack's pack model (the same one behind the pack simulator) — not an official rate. Grading odds are the real cumulative PSA population, which skews toward nicer, resubmitted copies, so it overstates the true first-submission gem rate. Full grade-by-grade breakdown below.
Grade-by-grade ROI & risk-adjusted outcomesNet vs raw per target grade, plus the probability-weighted distribution
| Target grade | Est. value | Grading fee | Net vs raw | Multiple |
|---|---|---|---|---|
| PSA 10 | $255.00 | $73 | +$162 | 12.6× |
| PSA 9 | $34.00 | $70 | −$57 | 1.7× |
| PSA 8 | $16.00 | $70 | −$74 | 0.8× |
Net = graded value − raw value − grading cost (tier fee + ~$20 round-trip shipping), using PSA fees as of 2026-08-26; the paused PSA Value tier is excluded so this isn't overstated. Real outcome depends on the grade achieved; PSA 10 is best-case.

Market dataCross-market spread, EU price, momentum & community buzz
Card textAttacks, abilities, weakness / resistance / retreat
Evolves from Cubone.
If this Pokémon is your Active Pokémon and is damaged by an opponent's attack (even if this Pokémon is Knocked Out), the Attacking Pokémon is now Confused.
Your opponent's Active Pokémon is now Burned.
This attack does 50 damage to 2 of your opponent's Pokémon. This damage isn't affected by Weakness or Resistance. If a Pokémon is Knocked Out by this damage, put that Pokémon and all cards attached to it in the Lost Zone instead of the discard pile. (You can't use more than 1 GX attack in a game.)
Pokémon-GX rule: When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
