Scores are computed, not written: the same five criteria with the same thresholds run over every operator. Where a site publishes nothing on a criterion it drops out of that operator's average rather than counting as a zero. How we rate.
In short
Monster measured 104.2% coming back per dollar across 28,580 sampled pulls, with a typical rip of 79.8%. It publishes no buyback rate, so what a sell-back returns is not something we can state.

Our read on Monster
Monster is a card-rip site: graded pokemon and one piece packs, odds printed on every pack page. You buy a digital pack at a set price, open it to reveal one real graded card, and then choose an exit, ship the slab or sell it back. What separates the operators in this category is rarely the thrill; it's the exit terms and whether the published odds survive contact with the real pull feed.
Across 28,580 sampled pulls we measured 104.2% of every dollar coming back in card value, gross, before cash-out. The typical rip, the median rather than the average, is 79.8%. That gap is not a contradiction: it is what a one-card-per-pack format looks like when a small number of large hits carry the mean. Most rips land at or below the pack price, which is why we lead with the median everywhere.
The strongest pack in its catalogue on our board is Ultra at 80.8% typical from 2,003 pulls. The full catalogue, with the distribution behind each pack, is on the packs tab.
On the terms side: no buyback rate is published, so what a sell-back returns is not something we can state. The complete term-by-term picture, including everything the site does not state, is on the trust tab.
Their odds, packs and terms are theirs to change, and this page reflects what was published when we checked it on 2026-10-04. Rip within a budget you're happy to spend on the entertainment.

Monster: frequently asked questions
Is Monster legit?+
Monster pays out real, professionally graded cards from a vault, and we measure what actually comes back from its public pull feed rather than taking its odds on trust. Across 28,580 sampled pulls we observed 104.2% of every dollar coming back in card value, gross, before cash-out. Facts it doesn't publish are listed as not verified rather than guessed.
How do Monster payouts work?+
Monster does not publish a buyback rate, so we can't state what a sell-back returns. Shipping the physical card is the outcome we can verify.
What is the typical return on Monster?+
The typical rip, the median across sampled pulls, is 79.8%. The site-wide average is 104.2%: it sits higher because a handful of big hits carry it. The gap between those two numbers is the honest picture of a one-card-per-pack site.
How often do you get your money back on Monster?+
Across 28,430 openings we recorded on Monster, 29.9% came back worth at least what the pack cost. The rest landed below it. That is the number to plan around: one card per pack means most openings sit near or under the price, and the occasional big hit is what pulls the average up.
What is the biggest pull recorded on Monster?+
The largest single outcome we have on record is 2006 Pokemon Ex Holon Phantoms Pikachu #78 PSA 10 out of Starter, worth 4818.0% of the pack price. It is one opening out of 28,430, so treat it as the tail of the distribution rather than something to expect.
Are the expensive packs on Monster better value than the cheap ones?+
Not automatically, and the data lets you check rather than guess. In the $25 to $99 band we recorded 10,282 openings, of which 30.4% came back worth at least the pack price. In the $500 and up band, across 3,883 openings, that figure is 30.1%. So the cheaper packs returned the price more often here, which is a fact about Monster and not a rule that carries to other sites.
Do Monster's published odds match reality?+
We compare every stated tier against what we actually recorded. The widest gap on Monster is the common tier of Ultra: advertised at 69.8%, observed at 59.1% across 1,183 openings. That gap runs against the buyer. Gaps this size need a large sample before they mean anything, which is why we only report tiers with at least 200 recorded openings.

Share of openings by what the card was worth against the pack price. One card per pack, so the bar on the left is the ordinary outcome and the tail on the right is what people remember.
Does paying more change the odds?
| Pack price | Packs | Openings | Got the price back | Typical rip, per pack |
|---|---|---|---|---|
| $25 to $99 | 1 | 10,282 | 30.4% | 80.0% to 80.0% |
| $100 to $499 | 3 | 14,265 | 29.4% | 78.0% to 80.0% |
| $500 and up | 2 | 3,883 | 30.1% | 78.0% to 80.8% |
The last column is the range across the individual packs in that price band, not an average: each pack's typical rip is a median, and medians of different packs cannot be averaged into one. Bands with fewer than 200 recorded openings are left out entirely.
Do the published odds hold?
On Ultra, the common tier is advertised at 69.8% and came in at 59.1% across 1,183 recorded openings. That is the widest gap between stated and observed odds we found on Monster, and it falls against the buyer.
In October 2026 we recorded 3,216 openings on Monster, with a typical rip of 79.0%. See how every site did that month.
