What makes a DSG holder
Encapsulation is more than a case — it's preservation, authentication, and presentation in one sealed package. Every DSG holder is engineered to keep a card exactly as it arrived, and to make that card easy to verify for years to come.
Polycarbonate
A shatterproof polycarbonate casing safeguards your card — 25× stronger than acrylic.
UV-Resistance
A UV-resistant slab shields cards from harmful light, helping prevent fading, discoloration, and damage.
Crystal clarity
An optically clear holder lets you read every detail on both the front and back of your card.
Fully sealed
Each card is enclosed in a fully sealed holder, so once it's slabbed it stays exactly as graded.
Card ID
Every encapsulated card receives a unique card ID, making it easy to identify within the DSG database.
QR Code
A scannable QR code on the label links straight to the card's grade report from any mobile device.
How your card gets encapsulated
From the moment a card arrives to the day it ships back, every step is handled to protect the card and document it clearly.
Receive & inspect
Your card is logged in and examined for authenticity and condition before anything else happens.
HD imaging
High-definition images of the front and back are captured to document the card and aid assessment.
Encapsulate
The card is sealed in a custom-fit, UV-resistant polycarbonate holder sized to its exact format.
Label & verify
A label with your unique card ID and a scannable QR code is applied, then the slab is ready to ship.
A holder for every kind of card
Standard cards aren't the only thing worth protecting. DSG builds specialty encapsulations for thick cards, vintage formats, pennants, custom art, and even ticket stubs — all in the same UV-protected, 25× polycarbonate. Tap any slab to see it larger.
Premium Thick Cards & RPAs
Up to 200ptRobust holders for premium patches, relics, and rookie patch autos — built to protect thick cards up to 200pt.
Vintage Tallboys
Topps · Fleer · ClassicSlim, custom-fit cases designed for the taller vintage tallboy formats from Topps, Fleer, Classic, and others.
Vintage Bowman & Undersized Sports Cards
Snug, custom-fit holders sized for early Bowman issues and other smaller-format vintage sports cards.
Vintage Pre-War Era Cards
Encapsulation tuned to the delicate tobacco- and caramel-era cards of the pre-war years, when sizes varied widely.
Pennant Cards
Single & DualCustom frames for pennant-shaped cards, available in both single and dual configurations.
Authentic
Verified, noted on labelThe Authentic designation is reserved for cards that are 100% genuine but have a condition that would make a numeric grade unfavorable. The specific issue — size, inked, shaven, and so on — is noted right on the label. This is common with vintage cards that don't size to modern standards, or when a collector simply wants confirmation a card is real rather than counterfeit, without concern for the grade.
Art Cards & Custom Cards
Showcase original art cards and custom creations in a clear, protective slab built to display them at their best.
Concert, Sports & Event Tickets & Stubs
Up to 2-1/2″ × 4-5/8″Preserve concert, game, and event ticket stubs in a sealed holder. The maximum size currently encapsulated is up to 2-1/2″ × 4-5/8″.
We are not currently authenticating after market autographs. All after market autographs must be authenticated by JSA in order to be graded and encapsulated.
