The problem

Pokémon is the hottest collectible on earth — and eBay is flooded with perfect-looking fakes. The word “proxy” hides at the bottom of a description. The cert number is blurred. The $1,000 card sits in a category eBay never inspects.

🃏

Proxy infiltration

Gold metal customs and bootleg grails slip into search results, with “reprint” buried in fine print.

🔒

Slab tampering

Real cert numbers paired with fake cards in replica slabs — or labels cropped out of the photos.

🕳️

AG evasion

High-value cards hidden in “lots” or odd categories so no one physically authenticates them.

📦

Pack & box tricks

Resealed boosters and “unweighed” vintage packs that fool newer collectors.
