How we check listings
These checks apply to every listing on the site. They are automated and not perfect — always open the eBay listing and check its photos and description before buying.
- The listing title is matched to one exact catalogue printing - name, set, collector number, card form (Mega, ex/EX/GX, and similar) and language all have to agree, or the listing is left off.
- The asking price (item plus shipping) is compared against a recent-sold market reference for that card and condition. Raw and graded cards use separate references.
- Listings that look like the wrong card, the wrong printing, a proxy, a reproduction, or something that isn't a single card (empty wrappers, sealed product, merchandise) are excluded.
- Selected higher-risk listings get an extra image check that compares the listing photo with the card's expected official printing; clear physical fakes and wrong-printing photos are hidden.
- Listings that end, sell, or go too long without being re-seen in an eBay scan stop being shown as live deals.
