Vintage & Modern
We grade all eras of Pokémon TCG — 1st Edition Base Set, WOTC era, modern sets, Japanese promos, and everything in between.
Holographic & Foil
Special attention to foil layer integrity, holo pattern condition, and surface micro-scratches invisible to the naked eye.
Promo Cards
McDonald's promos, Prerelease stamped cards, tournament promos — all graded with the same ultra-strict standard.
Grading Impact
A Charizard in a PSA 10 sells for multiples of raw value. An HGG Grail carries the same weight with full microscopic documentation.
Why grade your Pokémon TCG cards?
A professionally graded card in an official HGG slab carries significantly more value on the secondary market. Buyers trust independently verified grades — and with HGG's ultra-strict standards, a high grade means even more.
Our high-tech digital microscope equipment examines every corner, edge and surface of your Pokémon TCG cards with extreme precision. Every grade is earned, documented, and verifiable online.
