How we calculate prices

The rules, with the numbers. Nothing you can't verify.

What the MNM is

MNM stands for Minimum Near Mint. It is Nearmint's price: what a copy of that card, in that language and in Near Mint condition, really costs today, buying it from someone who sells for real.

It is not the lowest price that shows up on Cardmarket. That is one listing — often a private seller with a single copy, a blurry photo and six euros of shipping, maybe a damaged copy. The MNM is an average of the lowest listings in Near Mint condition, with a condition on the sellers that makes it hard to fake.

The rule, step by step

  1. Take the card's listings on Cardmarket, filtered by language, from the cheapest up. Price without shipping.
  2. Only Near Mint listings enter (or Mint, which is better — on Cardmarket the “minimum condition: Near Mint” filter does exactly this). An Excellent, Good or worse copy does not count, even if cheaper: the MNM is the price of a card in great shape, not of any card. That is where the name comes from.
  3. Take the 3 cheapest. If at least one professional seller is among them, the MNM is the average of those 3.
  4. If none is professional, add the next professional seller. Private sellers more expensive than the third never enter. So 3 or 4 prices, no more: the rule is made to be copied by hand.
  5. If there are fewer than 3 listings, average the ones there are. If the whole page has no professional, the average is still made and the MNM is marked as not anchored: there is a value, but it is known to rest on fewer guarantees.
  6. The result is rounded to the cent, once.

Example 1. The three cheapest listings are 170 · 200 · 200 €, and at least one of those sellers is professional. The MNM is the average of the three: 190 €.

Example 2. Same three, but all private sellers. The fourth listing is a private seller at 230 € — it does not count. The fifth is a professional at 250 €: it enters. The MNM is the average of the four prices 170 · 200 · 200 · 250: 205 €.

Example 3. A rare card with two offers in total: the MNM is their average. With four offers, all private: average of the first three, marked as not anchored.

eBay sold listings and the value of graded cards

The MNM says what a card costs today. eBay can say what it was paid: completed listings are real sales, not asking prices. eBay does not open this data to any program, but the sold-listings page can be opened with the filters already set — name, set, number, sold only. Every card page has that link.

From there it works like the MNM: whoever has the page in front of them copies the last three prices the card sold for (shipping excluded), the report goes into voting for 48 hours, and the value is their average. One or two sales are enough, if there are no more.

Grading is the same thing with one more word in the search. A card certified PSA 9, PSA 10 or Beckett Black Label is another object, with another market: its value is reported separately, per grade, from the last three sales with that grade in the title. Check that the listing really is this card, with that grade, in that language: an English PSA 10 and an Italian one are not worth the same.

These values do not enter the MNM or the chart: they are another marketplace. They live in their own table, with the date and how many sales make them up.

Is grading worth it?

Every card page has a calculation, not advice. It starts from the raw card's price, subtracts fee and shipping, and for every outcome — 10, 9, less than 9 — says what is left in your pocket compared with keeping it as it is. Graded values are those reported by the community from eBay sales: if they are missing, the calculation says so and is partial.

You choose the odds. We do not see the card: saying “likely PSA 10” from afar would cost you the fee. Three profiles — flawless, very good, average — with stated percentages, and the expected value is the average weighted by them. Change the profile and the verdict changes: that is how it should be.

An 8 counts at its own value if someone reported it, otherwise as raw; from 7 down it counts as raw: a PSA 7 sells like an ungraded card, and whoever paid the fee lost it. In the calculation that outcome is worth the raw price minus the costs.

The suggested fees are the indicative per-card fees of the European collection centres in 2026 — you can change them in the form:

Company and tierFeeNotes
PSA Value~30 €for cards up to ~$500 declared value; long turnaround
PSA Regular~55 €up to ~$1,500; faster
Beckett (BGS)~45 €with subgrades; the Black Label is a 10 with four 10 subgrades
CGC~22 €the cheapest; smaller secondary market
Return shipping~20 €insured, to the European collection centre

Grades you can report: PSA 6 to 10; Beckett 8, 9, 9.5, 10 and Black Label.

How we count income and outgoings

The collection value says what it would be worth today. The hobby account says something else: how much money went out and how much came back, month by month. Outgoings: purchases (shipping included), opened packs, and expenses without an asset behind them — supplies, grading, shipping, fairs. Income: sales net of fees and shipping paid by you, i.e. what reached your account, not the price written in the listing.

When you sell, the fee starts from the platform's typical percentage (Cardmarket 5%, eBay 13%) and can be corrected: you see the net before confirming. The ledger keeps the three numbers as you wrote them — price, fee, shipping — and does not recalculate them later: the ledger is never edited. A purchase whose price you do not remember stays out of the account and is counted separately: adding zeros would make something merely forgotten look free.

Everything can be downloaded: as Excel (five sheets — summary, collection, movements, pack openings, expenses — with real numbers, not text), as PDF (a snapshot to keep: totals, pie, hobby account and the collection by value) or as CSV. The files' totals are the page's totals, computed by the same functions.

Points: whoever reports, pays less

Every report — an MNM, eBay sales — that gets confirmedby the others' votes or by an admin is worth one point. A point is one cent off the subscription, when there is one: 100 points, one euro. At most 100 points a month. Whoever is here from the start accumulates them from now.

Three rules, all for the same reason: a point is worth something, and what is worth something must be defended. The point only arrives with confirmation, not with submission. If a confirmed report is later refuted, the point goes back. And whoever verifies their own report (admins) earns nothing. Points are separate from reputation, which is another thing: reputation is how much your vote weighs, and it cannot be spent.

Alerts: an email when a price crosses your threshold

Every card and every sealed product has “Alert me when the price changes”: pick a threshold, below or above, and the morning the reference pricecrosses it you get an email. The reference price is the page's own: the MNM if there is one, otherwise a community price, otherwise the price guide.

One email a day, with all the triggered alerts inside: no bursts. A triggered alert sleeps for seven days, then watches again — if the price stays below the threshold we do not repeat it every morning. Alerts are managed from My alerts; at the bottom of every email there is a link to stop receiving them, which works without signing in.

Why professional sellers

A professional has a shop, a name, stock and a warranty obligation: they answer for what they sell. A professional among a group of close prices is a market. A private seller alone is a bargain, or a typo, or a card that will never arrive. The rule does not exclude private sellers — their listings enter the average like the others — but demands that the group be anchored to someone who sells for a living.

It is also why the MNM is hard to inflate: moving it would take fake listings from several professional sellers, not a number typed into a form.

Who transcribes the listings

People. Nearmint does not read Cardmarket automatically: by choice, and out of respect for its terms of use. Whoever has the page in front of them copies the listings — price and seller type — into the card's form, which calculates the MNM live and says how many are still missing. The transcribed listings stay visible to everyone under the report: an MNM without its listings would be a number like any other.

There is one automatic source: every day it detects the Cardmarket minimum across all languages and conditions. We show it as a comparison (see below), but it is not the MNM.

How voting works, and when a price is trusted

Every report carries the link to the Cardmarket page. Voters do not express an opinion: they open the link and say whether it matches. Voting lasts 48 hours — after that, those listings most likely no longer exist and a vote would verify nothing.

A screenshot of the page can be attached too: two hours later the link shows a different page, the screenshot pins what was there at that moment. It is optional, but a report with proof gets ahead in moderation. The screenshot is private: only voters and admins see it, never the card page. No machine reads it — a person looks at it.

The vote count stays hidden until you have voted: seeing it first leads to looking at what others said instead of opening the listing. You cannot vote on your own report. Every vote weighs one, whatever the voter's reputation.

A report becomes trusted when it has at least 3 votes and passes a statistical threshold (Wilson lower bound at 95%, ≥ 0.35): with 5 votes that is 4 out of 5 in favour; with few votes it is stricter, with many more lenient. Only once trusted does it feed the card's price and collection values.

A price outside a common-sense band — below a fifth or above five times the reference — is not rejected: it goes to an admin, who can confirm or refute it. A refuted price stays in the history but disappears from the charts. Admins' reports are born verified (with no reputation gain); the common-sense band applies to them too, because a wrong keystroke does not look at the role.

The “Cardmarket minimum” and its limits

For the vast majority of cards, and for recognised sealed products, we detect every day, automatically, the lowest price on Cardmarket and its trend. It is useful data, and we label it Cardmarket min., but with two stated limits: it is a single listing, and it is the minimum across all languages and all conditions — a damaged Japanese copy counts as much as a perfect Italian one. That is why, when there is a trusted MNM, it is the MNM you see large and the Cardmarket minimum next to it, as a comparison.

Sealed products

Booster boxes, Elite Trainer Boxes, bundles: users build the catalogue from the Cardmarket link. As soon as a product is recognised, its minimum arrives automatically every day like for cards; on top of that a price can be reported, with the same voting as cards. A sealed product is intact by definition, so the condition is not a choice; the language is the edition's.

Reputation

Whoever reports earns +1 for every favourable vote and +10 when the report becomes trusted or is verified by an admin. A refuted report costs −25. The asymmetry is deliberate: cheating must cost more than it pays. Reputation is visible next to every report, but does not weigh on votes — a high reputation does not decide other people's prices.

History

Every recorded price stays forever: the charts start the day Nearmint went online and grow from there, one day at a time. There is no cleanup of old data. The value of your collection over time is rebuilt from what you owned that day times what it was worth that day: if you sell a card in June, May's chart keeps showing it.

Missing a question? The admins read everything. Nearmint is not affiliated with Cardmarket, The Pokémon Company or Nintendo.
