What's new
  • Centering, measured automatically: every scan now reads your card's border alignment from the photo.
  • Tells you the grade ceiling: the best PSA grade that centering allows — e.g. "centering caps this at PSA 9".
  • Where to find it: a new column in your scan results, on every card.
  • Status: BETA. Centering only for now — corners, edges and a "worth grading?" verdict are next.
  • Cost: free, included in every scan.

Most collectors find out a card was never going to grade a 10 after they've paid for the submission and waited five months. Centering is the most common reason a clean-looking card comes back a PSA 9 instead of a 10 — and it's the one defect you can measure from a photo before you ever ship the card. That's what Grade Estimate does, and starting today it runs on every scan.

Scan a card and CardPulse now shows its centering and grade ceiling alongside its price — raw vs PSA 9 vs PSA 10 — so "is this worth grading?" is one screen, not a guess. Try CardPulse free →

Why Centering Decides Your PSA Grade

PSA grades a card on four things: centering, corners, edges and surface. Centering is the easiest to assess objectively — it's just the ratio of the borders left-to-right and top-to-bottom — and it's a hard ceiling. A card with perfect corners, edges and surface but off-centre borders cannot reach Gem Mint, no matter how clean the rest of it is.

PSA's published front-centering tolerances run approximately like this (always verify on PSA's site before submitting):

  • PSA 10 (Gem Mint): about 55/45 front centering or better.
  • PSA 9 (Mint): about 60/40 front.
  • PSA 8 (NM-MT): about 65/35 front.
  • PSA 7 (NM): about 70/30 front.

So a card sitting at 62/38 is, on centering alone, a PSA 9 ceiling — submitting it expecting a 10 is paying $25–$40 plus months of waiting to confirm what the borders already told you. Knowing that before you ship is the entire point.

What Grade Estimate Does

When you scan a card, CardPulse now detects the card's outer edge and inner frame, measures the four border widths, and converts them into a left/right and top/bottom centering ratio. From that ratio it reports the highest PSA grade centering allows for that card. It doesn't promise you'll get that grade — corners, edges and surface still have to hold up — but it tells you the best case, which is exactly the number that decides whether a submission makes financial sense.

Pair that with what CardPulse already tracks — separate price histories for raw, PSA 9 and PSA 10 versions of the same card — and the grading decision becomes arithmetic: PSA 10 price minus raw price minus grading cost. If the centering caps you at a 9, you compare against the PSA 9 premium instead, which is often far thinner.

How It Reads Centering From a Photo

The hard part is that a phone photo isn't a scanner bed. Cards are shot at slight angles, under uneven light, and very often inside a penny sleeve or toploader whose edges look a lot like the card's own border. Grade Estimate compensates for the sleeve: it looks for the double dark-to-light transition a sleeve creates and, when most sides agree it's there, treats it as the sleeve rather than the card edge. An isolated transition on a single side is read as a design element, not a sleeve.

This is why it's a BETA and not a finished verdict. On a clean, square-on, well-lit photo the centering read is solid; on a tilted or glare-heavy shot it can miss or decline to estimate rather than give you a wrong number. The fix is mostly on your side and ours: shoot square-on, fill the frame, avoid hard glare — and we keep widening the range of photos it handles.

What It Can't Do Yet — and What's Coming

Being honest about a BETA: today Grade Estimate measures centering only. It does not yet assess corners, edges or surface, and it does not detect creases, print lines or whitening. So it tells you the grade ceiling centering imposes, not your final grade. A card that passes centering for a 10 can still come back a 9 on a soft corner.

Here's the roadmap, in the order we're building it:

  • Corners and edges — the next two grading factors, so the estimate moves from "centering ceiling" toward a fuller condition read.
  • A "worth grading?" verdict — combining the grade estimate with the live price spread (raw vs PSA 9 vs PSA 10) and the current PSA submission cost to answer the only question that matters: does grading this specific card make you money?
  • Wider photo tolerance — more reliable reads on angled, sleeved and low-light shots.

We'll keep posting updates here as each piece ships. If you scan a card and the estimate looks off, that feedback is gold while we tune it — reply to any CardPulse email and tell us.

How to Try It

It's already live. Create a free account, open the scanner, and photograph any card square-on. The centering and grade ceiling appear in your scan results next to the card's price. Free for up to 50 cards, no submission required — the whole idea is to tell you whether a submission is worth it in the first place.
