moonstone Pro · membership
The whole dossier. And the call we get graded on.
Free readers get the verdict stamps. Pro breaks the seal on 48,226 card dossiers and 218 set dossiers: the stamped buy, hold or sell, the 180 day target price, verified sold medians with their sample sizes, and grading EV with the full break-even ledger.

What the $9.99 opens
Eight things change the moment the membership starts. Every one of them is a limit in the code, not a promise in a brochure.
- 01The target price and the stamped call
Without a membership a rated card shows you one bit: whether the 180 day target sits above or below today's price. Pro shows the target itself, the upside to it, the BUY / HOLD / SELL stamp, and the cohort the number is anchored to.
- 02Every Market Report, unsealed
48,226 card dossiers and 218 set dossiers are built and waiting, and any card in the 63,600 card catalog builds one on demand. Free readers see the masthead and the verdict labels; members see the numbers underneath them.
- 03Verified sold medians, with the n
12,592 cards carry PSA sold medians checked against individual eBay sold listings, and 24,224 carry registry depth. The report prints the median, the sample size behind it, the weekly velocity and the gem rate drift.
- 04Grading EV with the break-even ledger
Not a multiplier over a raw price. The submission cost, the grade distribution, the break-even, and the arithmetic that got there, on every card whose tape is deep enough to carry it.
- 05Cynthia, 300 questions a day
Against 25 a day signed in and 5 for a visitor. A member is also never queued behind free traffic: the daily model budget holds back a reserve that only members can spend.
- 06Bulk scanning, and no scan ceiling
50 binder and showcase pages a day instead of 1, and the 600 a day fair-use ceiling on single card scans comes off entirely.
- 07A collection with no cap
A free collection holds 50 cards. A membership removes the ceiling, and nothing already saved is ever deleted to sell you anything.
- 08200 Scan API calls a month
The card recognition API that the developer plans sell, included at 200 calls a month against the 25 a free account gets. Higher volume has its own plans.

Open the report directoryWe publish the call before we know the answer
Every call is stamped with a date, a 90 day horizon, and the falsifier that would kill it, written at stamp time. 2,290 calls are on the clock right now across 482 cards and 1,111 frozen editions. None has reached its horizon yet, so nothing has been scored.
The scoreboard is public and it is not behind the paywall. Read it before you decide whether the calls are worth $9.99.

What you will not find on this page
No testimonials, no customer count, no countdown, no founder pricing that expires on Friday. The membership is new and there is nothing to boast about yet, so this page makes its case with figures you can check instead: 2,290 dated calls with published falsifiers, 135 studies whose methods are printed, 1,150,986 recorded price observations behind them, and a scoreboard that will list the misses first.
