Compz scans over 1 million cards each week, scores the top opportunities for grading ROI, and gives you a full decision desk — from discovery to returned grade.
Not a pick list. A grading operating system — discover, evaluate, track, and improve every submission decision.
Not because collectors are careless — because the research is genuinely hard. Raw comps, PSA 10 sales history, grade population, current fees. By the time you pull it all together, the window is usually already closed.

Where most people get this wrong
They see $738 → $4,900 and assume it's a home run. They skip the fee tier, assume 100% gem rate, and ignore the 3-month wait. After all costs at a realistic hit rate, the real number is what matters — and Compz shows it before you commit.
A card that looks profitable on the surface often isn't once you account for everything.
Raw price alone tells you nothing.
A $40 card with a $180 PSA 10 comp is a worse bet than a $90 card with an $800 PSA 10. The spread is what matters — not the sticker price.
Grading costs aren't flat.
Faster turnarounds cost more. High-value cards fall into higher fee tiers automatically. A $2,500 PSA 10 comp triggers a completely different submission cost than a $400 one.
PSA 10 prices shift weekly.
Last month's comp isn't this month's market. A card that made sense 4 weeks ago may have already been arbitraged out by the time you submit.
Opportunity cost is real.
Capital sitting with PSA for 3 months isn't working for you. Our model penalizes slow turnaround tiers — because time has a price.
We do the research. You make the call.
01
Every card across basketball, baseball, football, Pokémon, and more — pulled from real market data, not scraped averages.
02
Last 5 years only. Cards with real market volume and liquid PSA 10 comps. Everything else is cut.
03
~16,000 top opportunities get daily pricing updates. PSA tier, eBay fees, time cost, opportunity cost — all in.
04
Save the best candidates to your Grading Desk and follow the decision from wishlist to owned raw, PSA submission, returned grade, and sale.
We built Compz to pass the smell test — not to show you the best-case scenario.
Grading fees at the correct PSA tier
High-value cards hit higher fee tiers. We route each card correctly — not a flat $25 estimate.
eBay's ~13% cut is baked in
ROI is calculated on what you actually pocket, not the sale price.
Average comps, not outlier sales
We use average completed sales. One lucky sale doesn't make a card a good bet.
Thin markets are flagged
Cards with low sales volume get a lower confidence rating. You always know how liquid the opportunity is.
The grading operating system
Compz connects every step of the grading decision — from spotting an opportunity to comparing your expected grade against the actual result.
Over 1M cards scanned weekly. Top opportunities refreshed daily with current pricing, PSA tier, eBay fees, and time cost — all in.
Check the PSA 9 downside, surface risk, and submission economics before spending a submission slot.
From wishlist to returned grade. Track raw cost, expected grade, actual grade, and realized profit.
Understand what separates a gem candidate from a wasted submission. Build a sharper grading eye over time.

Decision system
Most collectors already track raw cost, PSA 9/10 comps, grading fees, selling fees, and target grades somewhere. Compz brings that workflow into the same place as the opportunity list.
Is Compz just a weekly list?
No. The list helps you find opportunities. The Grading Desk helps you track the grading decision afterward — from wishlist to owned raw, PSA submission, returned grade, and eventual sale.
Is this a full collection tracker?
No. Compz is built for grading candidates and ROI decisions, not cataloging every card you own.
What do I get for $19/mo?
Full access to the grading opportunity list plus Grading Desk, including up to 100 tracked grading decisions.
Is this just eBay sold listings in a spreadsheet?
No. We pull raw prices and PSA 10 comps, then run a full ROI model that includes grading tier selection, eBay fees, time cost, and opportunity cost of capital. That calculation — done correctly across 1M+ cards weekly with daily pricing refreshes on the top opportunities — is the part that takes hours manually.
What if the card doesn't PSA 10?
Our model assumes a 60% PSA 10 rate, not 100%. If the ROI is still positive at that hit rate, it's a real opportunity — not a best-case scenario.
How is this different from doing the research myself?
It isn't — we scan over 1 million cards each week and refresh daily pricing on the top opportunities so you don't have to. Even at 30 seconds per card, manually covering what we do would take thousands of hours. One avoided bad submission covers 3+ months of Compz.
What grading costs does Compz assume?
PSA tiered pricing based on each card's PSA 10 market value. We also apply an 8% annual opportunity cost for capital tied up during turnaround — because slower tiers have a real cost.
What's covered?
Basketball, baseball, football, and Pokémon. More sets and sports added regularly.
Can I cancel anytime?
Yes. Cancel from your account page, no questions asked, no waiting period.
One avoided bad submission covers months of Compz. Get the opportunity list, the decision desk, and the grading intelligence — in one subscription.
