What it sold for,
next to what they want

Open any card listing on eBay and BankTCG puts a panel beside the price: the median of recent sold listings for that exact card at that exact grade, and how far the asking price sits from it.

  • Sold comps matched on card, number and grade — not asking prices
  • Every listing priced free — no cap, no trial
  • Listing panel on 14 eBay sites, deal badges on 8
  • Pokémon · Yu-Gi-Oh! · Magic · One Piece

The BankTCG panel on an eBay listing for a BGS 9 Rayquaza, showing a Steal call at 84% below market, a $670 market price against the $108 asking price, and recent sales
A real listing, not a mockup. This BGS 9 Rayquaza was asking $108 against a $670 median.

What the panel tells you

Everything below is on the listing you are already looking at.

Free

Market price

The median of recent eBay sold listings for that card, at that grade. Not an asking price, not an average dragged around by one outlier.

Free

Deal call

Steal, Great, Good, Fair or Above market — based on how far the asking price sits from that median.

90-day history

A sparkline of the sales behind the number, so you can tell a $600 card that has been climbing from one that spiked once.

Recent sales

The individual sold prices and the dates they sold on. The number is shown with its working out.

Add to portfolio

One click puts the card in your BankTCG portfolio, matched to the right set, number and grade. The panel names the card it matched, so you can check it.

Alt+B to scan

Drag a box around any card image, on any page. BankTCG identifies it and prices it. Useful when a seller’s title tells you nothing.

How the price is worked out

A price you can't check is just a number someone told you.

It is a median, not an average. One mispriced sale can drag an average a long way. The median of the matched sold listings is what the panel shows.

Comps have to match the card. A sold listing naming a different card number is thrown out. A graded comp has to name the same grade — a PSA 10 is not evidence for a PSA 8.

The window stretches for rare cards. The default is the last 90 days. For cards that trade rarely it widens to 180 or 365 days, because three sales in a year still deserve a price.

These are estimates built from public eBay sold listings. They are not appraisals, and nothing here is investment advice.

Free and Legendary

Pricing every listing is free, forever. Legendary adds the evidence behind the number and somewhere to keep the card — $5 a month or $45 a year.

Getting started

1

Add it to Chrome

Install from the Chrome Web Store, then sign in with Google to create a free BankTCG account. That account is what your portfolio syncs against.

2

Browse eBay as usual

Open any card listing. The panel appears beside the price on its own — there is nothing to click first.

3

Check the comps before you bid

Read the median, the deal call and the sales behind it. Add the card to your portfolio if you buy it.

Your privacy matters

Exactly what it reads, what it sends and what it never touches.

What it reads

The card listing and search pages you open on the eBay sites above — the title, price, condition and any grading details shown. Nothing on any other site.

What it sends

Those listing details, so our servers can return a market price. Cards you add and alerts you set are stored against your BankTCG account.

What it never touches

Your eBay username, password or purchase history. It does not track your browsing outside eBay card listings, and we do not sell data.

The full policy, including where data is stored and how to remove it, is in section 5 of our privacy policy.

Questions

Where does the market price come from?

It is the median of eBay sold listings that match the card, its number and its grade. Comps naming a different card number are thrown out, and graded comps have to name the same grade. The window is the last 90 days, widening to 180 or 365 days for cards that trade rarely, because three sales in a year still deserve a price. These are estimates built from public sold listings, not appraisals.

Do I need an account?

Yes, a free BankTCG account. It is what the pricing calls are made against, and it is what syncs your portfolio to the BankTCG app on iPhone and Android. Signing in uses Google, and we never see an eBay password.

How do price alerts reach me?

By email, to the address on your BankTCG account. A poller checks eBay every 15 minutes and mails you when a matching card lists below the price you named. Alerts are part of BankTCG Legendary.

Which eBay sites does it work on?

The listing panel runs on 14 eBay sites: ebay.com, ebay.co.uk, ebay.com.au, ebay.de, ebay.fr, ebay.it, ebay.es, ebay.ca, ebay.ie, ebay.at, ebay.be, ebay.nl, ebay.ch, ebay.pl. Deal badges on search results currently run on the first 8 of those.

Does it show NM/LP/MP prices by condition?

No. eBay sold data does not reliably carry a condition for trading cards, so a grade-by-grade table would be guesswork. Graded cards are priced against comps at the same grade; raw cards are priced against raw comps.

The rest of it lives in the app

Cards you add from eBay land in the same portfolio you scan into on your phone. The app adds the camera scanner, AI pre-grading with centering analysis, and eBay listing straight from your vault.
