Next Grails is a market-information tool for trading-card collectors. This page explains what our numbers and signals are, what they are not, and the risks of buying and selling cards.

The short version

  • Information only. Not financial, investment, tax or legal advice.
  • Signals are statistical estimates from past data. They can be wrong, and many don't work out.
  • Data can be wrong, late or incomplete. Check the card and the listing before you buy.
  • Card prices can fall, and cards can be hard to sell. You make your own decisions.

1. Information, not advice

  • Everything on Next Grails is for information and education only. It is not financial, investment, tax or legal advice.
  • None of it is tailored to you. Every member sees the same data and signals, and nothing on Next Grails considers your finances, goals or situation.
  • We are not a registered investment adviser, broker, dealer or financial planner.
  • We don't buy, sell, hold or grade cards for you, and we never hold your money. We don't offer shares in cards, pooled funds or any investment product.
  • You alone decide what to buy, sell or grade. For decisions that matter to your finances, talk to a qualified professional.

2. How our signals work

  • Potential, Heating up, Spotlight, Primed but thin, price drivers, Grade & flip and the Buy checker's results all come from formulas applied to past prices, sales, listings and grading population counts. They look for patterns that have happened before. They cannot know what will happen next.
  • A signal is a reason to look closer at a card, not a reason to buy it. Use it to decide where to look, then check the card yourself.
  • The Buy checker's labels, "Buy", "Buy to grade", "Fair price", "Pass" and "Can't tell", are short names for how a price compares with recent sales and our estimates. They are not instructions or recommendations to you.
  • Grade & flip profit figures are estimates. They assume a grade, fees and a sale price. Your real result depends on the grade the card actually gets, grading fees and turnaround, shipping, taxes and the price you sell at.
  • Signals can be late, can miss big moves, can flag cards that then fall in price, and can change when the data updates.

3. Records and results

  • When we show a record of how a signal did, we say how we measured it: the time period, the rules, and whether it is a replay of past data (a backtest) or picks made live at the time.
  • A replay is not the same as live results. The formula may have been built by studying that same history, and some inputs, such as today's population counts, were not known at the time.
  • Our records count every pick that met the stated rules, including the cards that lost value.
  • Past performance does not guarantee future results.
  • We don't know how members' own purchases turn out, so we can't tell you what a typical member earns. Your results depend on which cards you buy, when, what you pay, the fees, the card's condition and when you sell. Many signals don't work out, and you can lose money.

4. Card market risks

  • Prices can fall quickly and a long way, for example after a reprint, a new set, a change in demand or a jump in graded copies. A card can become worth very little.
  • Cards can be hard to sell quickly at the price shown. In a thin market, a few sales can move a price a lot.
  • Marketplace fees, shipping, taxes and grading costs reduce what you keep.
  • Grades are uncertain. Population counts change as more copies are graded.
  • Fake, altered and wrongly described cards exist. Check the seller, the photos and the card.

5. Where the data comes from, and its limits

  • Our data comes from third-party market data providers, publicly available marketplace data (such as listings and sales on eBay and TCGplayer), and population counts published by grading companies.
  • Most prices update once or twice a day (around 7 AM and 7 PM Eastern). Some data updates less often: population counts at most once a day, and for some games and older sets, prices and sales can be several days to a week old. eBay listings are checked every few hours, and some auctions more often. It is not real-time.
  • Data can be wrong. A sale can be matched to the wrong card or version, a lot or a damaged copy can be counted as a single card, sales can be missing, and updates can be late.
  • We clean the data with automatic rules, for example to spot lots, damaged copies and mismatched listings. These rules make mistakes too, in both directions.
  • Listings and auctions can change or end before you see them. Always check the listing on the marketplace itself.

6. Conflicts of interest

  • The people behind Next Grails, including its founder, collect and invest in trading cards. They may own, buy or sell cards that Next Grails shows or flags, including before or after a signal appears.
  • Signals come from the same formulas for every card. We don't change a signal or a ranking because of cards we own.
  • We don't take payment from sellers, marketplaces, grading companies or publishers to feature or rank cards.

7. Affiliate links

Today None of our links carry affiliate tracking, and we earn nothing when you click through to a marketplace or buy something there. If that changes, we will label each affiliate link as a paid link, right next to the link, and update this page and our Privacy Policy before any tracking starts.

8. Testimonials

  • Every testimonial on Next Grails comes from a real person who has used it, in their own words. We may shorten a quote, marked with "…", but we never change its meaning. We never write testimonials ourselves or have them written by AI, and we never use stock photos of people.
  • Under each quote we show how the person is connected to us, for example "Founder" or "Friend of the founder · free access". If someone got free access or anything else of value, we say so there.
  • We don't pay for testimonials or reviews.
  • We keep each person's written permission to quote them.
  • Some testimonials describe a member's own results. They are that person's experience, not a promise; individual results vary, and prices can fall as well as rise.

9. Trademarks

Next Grails is independent and not affiliated with or endorsed by any game publisher, grading company or marketplace. Their names are used only to identify their products. See Trademarks & copyright for the full notices.
