The short answer
The same Card Saver 1 and clear penny sleeves you would send to PSA
SGC asks for the same submission format the rest of the industry does: each card in a clear penny sleeve, then into a semi-rigid holder. There is no SGC-specific holder to buy. What makes SGC worth knowing about right now is the queue rather than the kit — PSA paused new submissions on all four of its Value service levels on 2 June 2026, so for a mid-value card SGC is often the only sensible route in.
An SGC submission needs exactly what a PSA submission needs: each card in a clear penny sleeve, that sleeved card in a semi-rigid holder, and the stack packed so nothing moves in transit. There is no proprietary SGC holder and no SGC-branded supply you have to buy. If you already stock Card Saver 1s and clear sleeves for PSA, you are ready to submit to SGC today.
What has changed is the reason to care. PSA paused new submissions on all four of its Value service levels — Value Bulk, Value, Value Plus and Value Max — on 2 June 2026 while it worked through a submission backlog that trade coverage put in the millions of cards. That removed the cheap routes into PSA. SGC's Standard service, reported at $50 per card for cards up to a $1,500 declared value with no membership requirement, became the practical option for a lot of mid-value cards.
The supply list
- Clear penny sleeves — one per card, clear rather than coloured or opaque. This is a stated requirement, not a preference.
- Semi-rigid holders — a Card Saver 1 or equivalent at the standard size for modern cards, sized up for thick or oversized stock.
- Rubber bands or banding — to keep the submission in ordered, labelled stacks rather than loose holders rattling in a box.
- A rigid outer box — a sturdy cardboard box rather than a padded envelope for anything beyond a few cards.
- Cardboard protectors — pads either side of the stack, which is what actually stops a package being bent in sorting equipment.
- Low-tack tape — for the outside of the package only. Never tape anything to a card or a holder.

1. Best overall holder
Cardboard Gold Card Saver 1
Cardboard Gold · Standard modern cards going to PSA
The semi-rigid holder PSA's own shipping guide points you toward, at the size its instructions name. If you submit standard-thickness modern cards, this is the default and the decision is made.
Why it takes this slot: The standard semi-rigid at the size every major grader's guidance names. Buy at 200-count and it covers SGC, PSA and CGC alike.
- Holder size
- 3 5/16" x 4 7/8"
- Card thickness
- Standard cards up to roughly 20pt
- Material
- Acid-free, PVC-free rigid vinyl
- Common pack sizes
- 50, 100 and 200 count
What it does well
- Matches the semi-rigid dimensions PSA's shipping guide specifies
- Consistent fit from pack to pack, which matters when you are loading 200 cards
- Thin enough to band and ship in bulk without a bulky box
Where it falls short
- A snug fit — a thick or already-curved card needs care going in
- Priced above generic semi-rigids precisely because it is the submission standard
#ad We link to the listing rather than printing a price that would be wrong next week. How we are funded
2. The sleeve that goes inside
Ultra Pro Platinum Soft Card Sleeves
Ultra Pro · The default penny sleeve
Clear, acid-free, consistently cut, and sold everywhere in 100-count packs. It is the sleeve every other sleeve gets compared to, and the one PSA's guidance effectively asks for: clear, not opaque.
Why it takes this slot: Clear, acid-free and PVC-free. Clear is the actual requirement — opaque or coloured sleeves cause delays at every grader.
- Size
- Standard 2 5/8" x 3 5/8" trading card
- Material
- Acid-free, PVC-free polypropylene
- Pack size
- 100 count, sold in multipacks
- Clarity
- Clear — grading-submission appropriate
What it does well
- Clear sleeve, which is what grading submissions require
- Consistent cut, so cards do not catch going in
- Cheap enough to sleeve a whole box without thinking about it
Where it falls short
- Thin by design — a sleeve is not protection on its own
- Static cling makes single-handed loading fiddly
#ad We link to the listing rather than printing a price that would be wrong next week. How we are funded
3. Best for fragile cards
Ultra Pro Semi-Rigid Card Holders
Ultra Pro · Easier loading on fragile cards
Ultra Pro's semi-rigid uses a pronounced, rigid top lip that opens without flexing the holder. On a soft-cornered vintage card that handling difference is worth more than brand loyalty.
Why it takes this slot: The pronounced lip opens without flexing the holder, which matters on the soft-cornered vintage that SGC is especially popular for.
- Format
- Semi-rigid with a pronounced half-inch top lip
- Material
- Acid-free, PVC-free
- Common pack sizes
- 50 and 200 count
What it does well
- The stiff lip pops open cleanly, so the card slides rather than scrapes
- Usually cheaper per unit than the submission-standard alternative
- Widely stocked, so bulk restocks are easy
Where it falls short
- Fit is slightly looser than a Card Saver 1 on a standard card
- Check the current dimensions against your grader's stated requirement before a big submission

4. Best for thick cards
Cardboard Gold Card Saver 4
Cardboard Gold · Thick patch, relic and jersey cards
The thick-card answer in the Card Saver family. When a patch card will not go into a CS1 without force, this is the holder that keeps the submission compliant instead of reaching for a toploader.
Why it takes this slot: Keeps a patch or relic card in a semi-rigid rather than a toploader, which no grader wants to receive.
- Card thickness
- Thick cards above standard, including many relics
- Material
- Acid-free, PVC-free rigid vinyl
- Format
- Semi-rigid, submission-friendly
What it does well
- Takes thick cards without forcing them, which is where corner damage comes from
- Keeps thick submissions in a semi-rigid rather than a toploader
Where it falls short
- Overkill and loose for standard cards
- Thicker stacks mean fewer cards per shipping box

5. Best mailer for the return trip
Duck Brand Kraft Bubble Mailers #0 (6x9)
Duck Brand · Graded slabs and small lots
The step up in size for anything in a slab. A PSA or SGC case will not fit a 4x8 mailer, and the #0 size is the smallest one that takes a slab plus padding.
Why it takes this slot: A 6x9 kraft bubble mailer is the right size for a small submission going out and slabs coming back.
- Mailer size
- #0 — 6" x 9"
- Exterior
- Kraft paper with bubble lining
- Closure
- Self-seal adhesive strip
What it does well
- Fits a graded slab in a sleeve with padding on both faces
- Kraft paper is curbside-recyclable in more places than poly
- A mass-market brand, so restocking it is never a hunt
Where it falls short
- Kraft paper darkens and softens if it sits in a wet mailbox
- Oversized and wasteful for a single raw card

Why SGC, and why now
Three practical reasons, beyond the PSA pause. SGC requires no paid membership to access its standard service, where PSA's cheapest tiers were made exclusive to Collectors Club members at a reported $149 a year. For a collector submitting a handful of cards annually, that membership cost can exceed the grading fees.
Second, SGC's stated turnaround on Standard service is reported at 40-plus business days, against the 90-to-100 business days reported for PSA's Standard tier when it was introduced in September 2026. Third, SGC has a long-standing reputation with vintage collectors, and its black-bordered slab is genuinely popular for pre-war and mid-century cards rather than merely tolerated.
The counterweight is resale. PSA's slab commands the broadest market and, for many modern cards, a measurable premium. That trade-off is the whole substance of PSA vs SGC, and the fee comparison is in SGC grading cost and PSA grading cost.
Packing an SGC submission
- Sleeve each card in a clear penny sleeve, with the sleeve opening facing the closed end of the holder so the card cannot slide out.
- Slide each sleeved card into a semi-rigid holder — square, with no force. If it binds, you have the wrong size.
- Order the holders to match your submission form exactly, so the cards arrive in the sequence the paperwork lists.
- Band the holders into stacks of a manageable size rather than packing loose holders, which shift and scuff in transit.
- Sandwich the banded stacks between cardboard protectors, then pack into a rigid box with the void filled so nothing moves.
- Seal the outside with tape, insure for the declared value you submitted at, and keep the tracking number.
The sequence is effectively identical to a PSA submission, which is covered step by step in how to package cards for PSA and how to ship cards to PSA. Read either of those as the generic packing method; only the address and the form change.
What to submit, and what to leave raw
The arithmetic does not change because the fee is lower. A card is worth grading when the expected graded value, minus the fee and shipping both ways, beats what the raw card is worth today. A $50 fee on a $40 card is money set on fire regardless of how short the queue is.
Pre-screen before you pay. Centering is the single most common reason a card misses a top grade, and an acrylic gauge plus a loupe costs a fraction of one submission fee — see best card centering tools. What the resulting grade labels actually mean is in the PSA grading scale explained, and which cards clear the bar at all is in what cards are worth grading.
If you were specifically looking for PSA's bulk route, read the PSA bulk submission guide first — the tier you are probably thinking of is paused, and that page explains what the alternatives are.
