Every single we list is checked closely by hand before it ships. We photograph and inspect each card ourselves, so what you see is exactly what you get. We only carry one copy of each card, so once it sells, it's gone for good. No restocks. No reprints.

What PSA Checks

Four things, every card

Centering

How evenly the front and back images sit inside the card's border. It's often the single biggest factor separating a 9 from a 10, and the one most new collectors overlook.

Corners

Whether all four corners stay sharp and fully intact under close inspection. Even the slightest whitening or softness at one tip can pull an otherwise clean card down a full grade.

Edges

A close look at chipping, roughness, or wear along all four sides of the card. Edges hold up differently than corners, which is why PSA scores them on their own.

Surface

Every scratch, print line, indentation, or scuff across the front and back gets weighed here. A truly clean surface under bright light is what separates the top grades from the rest.

After The Grade

Protecting your graded card

A slab keeps a card safe from handling, but the slab itself still needs looking after.

Keep it upright

A stand keeps a slab visible without your hands ever touching the case edges. It's a small habit that cuts down on the shelf-scoots and accidental drops that cause most slab damage.

Out of direct light

Sunlight fades labels and can yellow a card over months of display. If a graded single is going on permanent display, keep it out of direct sun or behind UV-filtering acrylic.

Store it locked, not loose

Once you're holding more than a couple of slabs, a lockable case keeps them stacked safely and travels well for shows — a lot safer than a drawer where cards can slide and scratch each other.

Double sleeve it — a penny sleeve over a perfect-fit sleeve seals out moisture and dust. We choose acid-free materials so nothing we sell ever damages your cards or collectibles. Silica gel packets pull microscopic moisture out of the air to protect your collection. Have a question or aren't satisfied? Real humans answer our support inbox. Follow @viora.cards on Instagram and TikTok for new drops first. Store cards upright, not stacked flat — weight bends corners over time. Magnetic cases are built for display. Toploaders are built for storage and shipping. UV-resistant cases help keep graded slabs from sun-fading near a window.

A grade doesn't set the price on its own — rarity and demand matter too — but it tells you exactly what condition you're getting, sight unseen. Every card we sell is authenticated with a real PSA cert number you can check yourself.
