Cardboard Journal's Take
GSG (Gold Standard Grading)
Searchable on eBay across all three card categories, and little else is established.
What Sets Them Apart
The largest grading operation in Europe, and it owns the room the European hobby meets in: GSG runs CARDVENTION, the continent's biggest card show, alongside the grading business. It publishes a population report, runs a counterfeit-detection programme, and offers cross-card, authentication and custom services beside standard grading.

What They Grade

- Non-Sports & Entertainment
- Autographs
Marketplace Acceptance
Listed in eBay's grader filter but not covered by the Authenticity Guarantee, so slabs above $200 receive no buyer protection. No auction house presence found.
Pricing
Not verified.
The Slab
Cases manufactured in Germany, sold on robustness and scratch resistance. A case-change service exists for damaged holders and a renewal service for regrades, both priced separately.
Example slab shown for reference — not a card I personally own.
The Label
SubgradesFour, on the label
Subgrades are optional and priced as an upgrade — roughly €20.99 without and €23.99 with. GSG publishes its subgrade calculation method and its grading scale as standing pages, which is more disclosure than most.
Grader Use Cases
- Resale Value
- Personal Collection
- Protection & Preservation
- Authentication
- Trading & Liquidity
- Display & Presentation
The European resale label with the most reach, and the only one on this site whose parent also runs the continent's biggest show.
Known Concerns
Being listed by eBay means buyers can filter for the slabs; it says nothing about how the grades are assigned. Public information is thin enough that this entry is deliberately sparse rather than padded with inference.
