The short version
1 min to read it all, belowThe score
Scores cover graders you can send cards to. This one is not taking public submissions, so it is not scored.

- Public cert lookupYes
What to watch
Nothing outstanding against the grading itself. The live issue is purely one of identification: millions of CSG slabs remain in circulation and a buyer encountering one today may assume the company vanished.
All known concernsPricing
No longer sold. Submissions go to CGC Cards.
The full file
What sets them apart
CSG was CCG's sports-card arm, launched in 2020 to sit alongside CGC's TCG grading. In June 2023 the two were merged into a single CGC Cards brand, which made CGC the second-largest grader in the hobby overnight.
Where the slab sells
CSG slabs remain covered by CGC Cards' guarantee of authenticity and grade, and remain searchable and saleable. Treat a CSG holder as a CGC holder for recognition purposes.
Turnaround
Folded into CGC Cards in July 2023. Submissions that would once have gone to CSG go to CGC.
The slab and the label
Subgrades: None
The Certified Collectibles Group holder — the same case body CGC and NGC use, which is why the transition to CGC Cards was visually seamless.
Example slab shown for reference, not a card the editor owns.
A blue CSG flip. Cert numbers still resolve through CGC's lookup, so verification did not break when the brand did.
What they grade
- Sports Cards
- Autographs
Who it's for
- Protection & Preservation
- Authentication
A holding label rather than a submitting one. CSG slabs stay eligible under eBay's Authenticity Guarantee, so there is no urgency to crack and resubmit.

It did not — it became CGC.
History
Certified Sports Guaranty launched in 2020 as the Certified Collectibles Group's sports-card arm, sitting alongside CGC's TCG grading under the same parent.
In July 2023 the two were merged into a single CGC Cards brand, which made CGC the second-largest grader in the hobby overnight. CSG slabs were not recalled and were never orphaned — the parent company still stands behind them.
