Online marketplace eBay has introduced an authenticity guarantee service for high-value trading cards in the UK. The program provides expert verification for eligible items priced at £500 and above.
The service began rolling out on 6 May 2026 across ebay.co.uk. It covers collectible card games, sports trading cards and non-sports cards, with full eligibility expected by June. Eligible listings display a blue authenticity guarantee badge, and the program also applies to purchases made through eBay Live.
