CollX: free scanner with a marketplace

CollX recognises sports, TCG and non-sport cards against a database it describes as 20+ million cards, returns an average market value, and lets you add cards to a collection and buy or sell in the CollX marketplace with tracked shipping options. CollX Pro costs $9.99 per month or $99.99 per year and includes unlimited collection capacity, CSV export, extra seller tools and a $10 monthly credit to buy cards. Independent reviewers note Pro also includes a monthly allowance of enhanced "Scan+" recognitions.

Best for: casual collectors and sellers who want quick values and an easy place to sell. Not for: condition grading.

Ludex: sold-price values and eBay listing

Ludex bases values on completed sales and focuses on helping you list on eBay from your portfolio. The free plan gives 200 identified scans per month and a 60-card portfolio. Lite ($4.99/month or $44.99/year) unlocks unlimited scans and portfolio in one sport or TCG category; Standard ($9.99/month or $89.99/year) unlocks everything with 50 eBay listings a month; Pro ($24.99/month or $239.99/year) raises that to 250 listings.

Best for: sellers who list regularly on eBay and collectors focused on one category. Not for: condition grading.

Card Ladder: data, indexes and value tracking

Card Ladder is known for its sales database, card and player indexes and collection-value tracking, which appeal to collectors who treat cards like an investment portfolio. It's most useful for researching price trends before buying, timing sales and understanding how a player's market is moving.

Best for: data-driven collectors and investors. Not for: quick scanning at a show or condition grading.

PreGradeCards: condition grading before you submit

PreGradeCards measures the physical card from your photos — centering ratios, corners, edges and surface — and predicts grades on PSA, BGS, CGC and TAG scales, with defect notes and market comps. It runs in Safari or Chrome with no download; new accounts get 2 free credits and the Photo Check is free. PreGradeCards reports about 89% agreement within one grade point on its validation, across more than 1.2 million processed images.

Best for: deciding which cards are worth grading and which company to use. Not for: replacing a full portfolio tracker or marketplace. Try it on your own cards.

Is CollX free? What about fees?

Yes — scanning and basic collection tracking in CollX are free. CollX Pro ($9.99/month or $99.99/year) is optional and adds unlimited collection size, CSV export, seller tools and a monthly marketplace credit. Selling on the CollX marketplace involves fees and shipping options set by CollX; check the current seller fee schedule in the app before listing, as marketplace fees change. Ludex is also free to start; its paid plans are about capacity and listing volume rather than marketplace commissions.

Scan accuracy: where scanners struggle

• Parallels and refractors — colour variants of the same card can be confused; always check the parallel.
• Reprints and same-art printings — especially in TCG; confirm set and number.
• Vintage variations — 1st Edition, Shadowless, error variants.
• Graded slabs — some apps read the label; others price the raw card.
• Low light and glare — both reduce recognition accuracy.

None of these apps verify authenticity — a convincing fake can scan as genuine. See our real-or-fake checker guide.

How each tool prices cards

Values differ between apps because they use different sources and methods: average market values, completed sales, marketplace listings and proprietary indexes. Differences are largest for thinly traded cards and for parallels. For grading decisions, look at sold prices for the exact card at the grades you might get — PSA 9 vs PSA 10 — not just a raw average. PreGradeCards shows sold and active comps with each grade so you can compare the predicted grade against the market.

Which should you use?

Best combinations

• Free stack: CollX or Ludex free + PreGradeCards free credits and Photo Check.
• Seller stack: Ludex Standard + PreGradeCards packs for pre-grading inventory before grading or listing raw with condition notes.
• Investor stack: Card Ladder + PreGradeCards to check condition on cards you're about to buy or submit.

For TCG collectors: where TCGplayer fits

Pokémon, Magic and Yu-Gi-Oh! collectors often add the free TCGplayer app, which scans every TCGplayer game and shows TCGplayer market price (iOS 17+, Android 9+). It's the most direct price reference for US TCG singles. Like CollX and Ludex, it identifies by artwork and doesn't grade. If its scanner stops working, see our TCGplayer troubleshooting guide.

Privacy and data ownership

Collection apps hold detailed data about what you own and its value. Check each app's privacy label, whether you can export your collection (CollX Pro offers CSV export), and what happens to your data if you cancel. Browser-based tools keep history in your account without installing an app. Avoid posting collection screenshots publicly with your address or location visible.

A practical weekly workflow

1. Scan new cards with your scanner of choice.
2. Flag anything worth several times a grading fee.
3. Pre-grade flagged cards; keep realistic 9–10s.
4. Choose a grading company with our decision guide.
5. List the rest raw with clear photos and condition notes.

Verdict

If you can only pick one app, pick by your main job: CollX for casual collecting and selling in-app, Ludex for eBay sellers, Card Ladder for market data. Then add PreGradeCards for the one thing none of them do — telling you whether a card is worth paying to grade. That combination costs nothing to start and prevents the most expensive mistake in the hobby: grading cards that come back an 8.

Sports cards vs TCG: which app is stronger?

CollX and Ludex both began with sports cards and remain strongest there — parallels, rookie variations and player tracking are well supported. Both have expanded into TCG, and Ludex lets you choose one TCG as your unlimited category on Lite. Card Ladder's indexes and data lean toward sports. For TCG-heavy collectors, TCGplayer's app is the price reference and a grader like PreGradeCards covers condition for both sports and TCG with CGC and TAG estimates that TCG buyers care about.

What a year of each actually costs

Most casual collectors never need a paid scanner tier. Subscriptions start to pay off when you list frequently or have a large portfolio to track. Grading credits only cost money in the weeks you're actually preparing a submission.

Using these apps at a card show

At shows, CollX and Ludex give fast values for negotiating; Card Ladder's data helps before you go. For condition, ask to see a raw card out of its top loader and photograph it — a quick pre-grade or at least a centering check on your phone prevents overpaying for a "definite 10". Keep your phone's brightness up and bring a small LED light for consistent photos under convention-hall lighting.

For bulk sellers and dealers

Dealers processing hundreds of cards a week care about speed, export and listing tools. Ludex's listing quotas and CollX's marketplace both help, and Card Ladder helps with buying decisions. Pre-grading fits upstream: run your high-value intake through an AI grade so you know which cards to send to PSA and which to list raw with condition notes. Listing raw cards with measured centering in the description builds buyer trust and reduces returns.

Final recommendation

Start free: one scanner for value and PreGradeCards for condition. Upgrade a scanner only when listing volume or portfolio size demands it, and spend grading credits only on cards whose value justifies a submission.
