Find them before the spike.

Next Grails reads real sales, how many copies PSA has graded, and live eBay listings, then shows you which cards to look at next. Six card games, one tool.

Get started See what it finds

    A price chart shows you what already happened. Next Grails shows you where to look next.

    Every day it reads the latest sales and counts the copies PSA has graded, and every few hours it scans what is for sale on eBay. When a card starts selling faster than usual, it moves to the top of a list, so you don't have to go looking for it.

    See the five lists

    How it works

    It reads. It scores. It tells you.

    1. It reads

      Every day: sales of graded cards on eBay, prices and sales of raw (ungraded) cards from TCGplayer, and PSA's population counts: how many copies of each card PSA has graded, and at what grade. Every few hours: what is listed on eBay right now.

    2. It scores

      Each card is measured against its own history and its own game: how fast it is selling compared with its usual pace, how rarely it gets a PSA 10, how scarce it is, and what similar cards sell for.

    3. It tells you

      Ranked lists you can read in a minute, a briefing in plain English, and a Discord alert when a card matches an alert rule.

    Who it is for

    Three ways to buy cards. Where to start with each.

    What it finds

    Five lists. Each one a different reason to look.

    Every list is ranked, every row is a real card, and every number is labeled.

    01Heating up

    Cards selling far faster than usual.

    When a card that barely sells starts selling every other day, something changed. Heating up ranks the cards whose graded sales have jumped furthest above their own pace.

    How it is measured

    • Graded copies (PSA 8, 9 and 10) sold on eBay over the last 30 days, compared with the card's own pace over the 90 days before that.
    • The ranking weighs how unusual the jump is, not just how many sold. A card selling more while its price falls ranks lower.
    • Two lists, not one. On a card under a year old, a jump in sales is mostly newly graded copies reaching the market, so new cards get a list of their own.

    A jump in sales shows where buyers are today. For what came after past jumps, see the signal scorecard under Insights.

    02Potential

    Scarce, hard-to-grade cards at a low price, and a record you can check.

    The potential score ranks cards over a year old on four traits that came before bigger price rises in Next Grails' own sales history: Hard to grade (a low gem rate, so few graded copies get a 10), Scarce (few PSA 10s exist), Aged (how long it has been out) and Room in the price (cheap for what the card is). Pokémon is scored on all four. One Piece and Lorcana are scored on the two that don't need PSA population counts, Aged and Room in the price, and their own record is still being built.

    How it is measured

    • Each of the four is the card's rank, 0 to 100, among the scored cards. The score is their plain average: each counts the same.
    • A card is scored when it is over a year old, PSA has graded 25 copies or more, and at least 6 of its PSA 10s sold in the last 60 days.
    • What did not come before bigger rises: the card's price already climbing, its raw price rising first, or the rest of its set rising. What mattered was supply, not buzz.

    03Grade & flip

    Buy it raw. Grade it. Know the math first.

    Raw cards worth sending to PSA, ranked by the profit left after PSA's fee, eBay's selling fee and shipping, weighted by how often the card really comes back a PSA 10.

    How it is measured

    • For every grade: what the slab sells for, minus PSA's fee (plus PSA's upcharge: an extra fee when the graded card turns out to be worth more than your service level covers), eBay's fee and shipping.
    • The average weights each grade by how often PSA gives it, from the card's own population report.
    • It is a best case and says so: people send in their best copies, so a raw card you have not checked closely will usually grade lower.

    04Deals

    Listings priced under the card's recent sales.

    Every few hours it scans eBay for Buy It Now PSA 10s priced below what the card has recently sold for. Then it does the part people skip: it checks the listing. Deep discounts are as often fakes or scams as steals.

    What it checks

    • The price, shipping included, against the card's usual PSA 10 price from recent sales.
    • The seller. A rating under 98%, or fewer than 50 ratings, is called out.
    • The cert number. The number on the PSA label links to PSA's own lookup, so you can check the slab against PSA's record; a listing without one is flagged.
    • Where it ships from, when that is not the United States.
    • The discount itself. At 50% under or more it reads: unusually cheap, check photos and cert.
    • The usual price itself. When most current listings ask far less than the recent sold price, Next Grails takes those sales to be mixed up with a pricier printing (another version of the card) and shows no deal.

    05Spotlight

    Who collectors are chasing, and what they have not found yet.

    When one card of a Pokémon takes off, buyers look at its other cards next. Spotlight ranks the Pokémon whose cards are heating up together (in One Piece and Lorcana, the characters), then lists their cards whose prices have not moved yet.

    How it is measured

    • Heating up, for a Pokémon or character, adds up three things: how fast its graded cards sell compared with their usual pace (half of that measured without its best-selling card, so one card cannot carry it), more of its cards spiking than chance would explain, and its prices rising.
    • Its cards on the list are the ones that have a sold price and whose price has not moved this month, ranked on scarcity, rarity, how cheap they are next to similar cards or their own recent high, and early signs such as sales picking up. Each one lists its reasons.

    Insights

    The market in plain English.
    And a scorecard for Next Grails' own signals.

    The briefing is not written by AI. Each sentence comes from a fixed rule applied to the numbers, and appears only when enough cards back it up. Under it is the signal scorecard. A signal is a rule that flags a card, such as Heating up or Low pop, and the scorecard publishes what happened to the cards each one flagged, good or bad.

      Where it fits

      Not a price chart. Not a collection tracker.

      Both are good at their job. Neither tells you which card to look at next.

      A price chart A collection tracker Next Grails
      The question it answers What has this card sold for? What are my cards worth today? Which card should I look at next, and why?
      Where you start With a card you already have in mind. With the cards you already own. With ranked lists of cards you have not thought of yet.
      What it looks at The price, over time. The price, times what you hold. The pace of sales, PSA populations and gem rates, live listings, and the price.
      What it is best at The long history of one card. Valuing a binder. If that is all you need, use one. Finding the card, checking the price behind it, and doing the grading math.
      What it will not do Tell you where to look. Point you to cards you do not own. Track your collection, sell you cards, or give buy and sell advice. It tells you where to look and shows its work; the decision is yours.

      Next Grails is new, so there are no member reviews yet, and none will be made up. Instead, here is how the cards its potential score ranked highest did when the score was tested on past weeks, and three of those cards with their prices.

        Questions, answered straight.

        What do raw, graded, pop and gem rate mean?

        Raw: a card that has not been graded. Graded: a card a grading company such as PSA has rated from 1 to 10 and sealed in a plastic case, called a slab. PSA 10 (Gem Mint) is the top grade. Pop, short for population: how many copies of a card PSA has graded, and how many got each grade. Gem rate: the share of graded copies that got a 10, so a low gem rate means a 10 is hard to get. Printings: the versions of one card, such as 1st Edition and Unlimited, or regular and Reverse Holo. Signal: a rule that flags a card for one reason, such as Heating up or Low pop.

        Where do the numbers come from?

        From completed sales: eBay sold listings for graded cards and TCGplayer sales for raw ones, plus PSA population reports and the eBay listings up right now. Each graded price lists the eBay sales behind it, newest first, with a link to each sale for as long as eBay keeps the listing online.

        Which games does it cover?

        Pokémon in English and Japanese, One Piece, Disney Lorcana, Riftbound, Gundam and Magic: The Gathering. Pokémon, One Piece and Lorcana have graded sales. Riftbound, Gundam and Magic run on raw prices for now.

        A deal 60% under the usual price sounds too good. Is it?

        Often, yes. Deep discounts are as likely to be fakes as steals, so every deal shows the seller's rating, the PSA cert number when the listing has one, and anything that looks off.

        How fresh is the data?

        Prices refresh every day. Sold listings arrive late and fill in over about a week (longer for One Piece), so every list shows the last day of sales it includes. eBay is scanned for deals every few hours.

        Does Next Grails sell cards?

        No. Deals link straight to the listing on eBay, and Next Grails never touches the sale.
