Each collectible type is judged on the criteria that actually matter for it. Below is exactly what we accept, and exactly what we look at.
Professional grading for modern and vintage TCG and CCG collections, sealed in a premium GLA slab with a printed label and unique certification number.
Rookies, parallels, autographed inserts and vintage issues, graded on the same four-factor standard used for trading cards.
Professional comic grading with archival protection. Books are handled with clean tools and sealed in an archival case sized to the issue.
Factory-sealed and complete-in-box titles, graded with a separate seal rating so buyers can judge the wrap independently of the box.
Carded and loose diecast graded on presentation as a whole — the card and blister matter as much as the casting.
Authentication and grading of collectible coins, sealed in an inert capsule that protects the surface without altering the toning.
Professional grading for collectible paper money, sealed in an archival sleeve that keeps the note flat and readable from both sides.
Authentication for signed collectibles, issued with a GLA Certificate of Authenticity and a permanent record in our database.
For selected events we also offer Witnessed Signature Authentication — a GLA representative watches the item being signed and documents it on the spot. Read how witnessed authentication works.
