Sales data

All-time basketball card sales

Every result on the all-time leaderboard has a direct sale-record link, with venue, sale date, currency, buyer's-premium treatment, and evidence status kept alongside the ranking.

Sales data

Player sales boards

Player boards now expose evidence status and direct-source availability row by row. The 198 records without direct links remain labeled as pending instead of being represented as fully verified.

Release history

August 31, 2026Board release
The merged release now powers 94 live player boards from 97 maintained record collections and 956 records. Direct links cover 758 records; the remaining 198 stay visibly marked as source pending.

Last verified: August 31, 2026
Source status: Source coverage in progress
Source count: 758 of 956 records direct-linked
Coverage: 94 live player boards · 97 maintained collections · 956 sale records

Direct-source coverage is incomplete. Pending rows remain usable as reported market observations, but the interface distinguishes them from direct-linked evidence.

Player research

Player card profiles

The latest profile release completed the legacy prose pass, kept all 660 buy-lane summaries distinct, and preserved attainable-target, consolidation-pilot, and player-specific safeguard tests.

Release history

September 1, 2026Content-quality release
All 660 legacy buy-lane summaries are distinct, normalized repeated eight-word phrase share is 0.9%, and the three explicit consolidation pilots remain preserved.
August 28, 2026Collector-lane audit
The monthly scarce-and-iconic review realigned vintage, Gold, RPA, and trophy roles and refreshed exact-card image evidence for active profiles.
August 5, 2026Methodology update
Entry, Core, Premium, Grail, and Trophy became collector roles; exact-card anchors kept numeric values while family and unique targets moved to price discovery.

Last verified: September 1, 2026
Source status: Evidence overlay audited
Source count: 399 unique external evidence links
Coverage: 154 audited records · 132 full five-lane profiles

The audit overlay retains source URLs for exact-card evidence and keeps unresolved or reference-only cards distinguishable from the written target recommendation.

Collector tools

The hub now connects nine live workflows and makes clear whether a result comes from maintained BCI data, a documented decision framework, or user-entered calculator assumptions.

Release history

September 2, 2026Workflow verification
The tools hub was checked as one nine-workflow collector path spanning card identification, grading math, player checklists, set comparison, repeat-sales research, saved research, player counts, parallel research, and set selection.

Last verified: September 2, 2026
Source status: Methods and inputs checked
Source count: 9 reviewed workflow definitions
Coverage: 9 live collector workflows

Tools use maintained first-party datasets or published BCI rules. Calculators are decision aids, not live market feeds, appraisals, or guaranteed outcomes.

How to read the register

Dates describe the published scope

A release date means the listed dataset scope was checked and published on that date. It does not imply that every external marketplace, population report, or checklist stops changing afterward.

Corrections

Material fixes stay visible

Report the exact page, card, sale, or checklist row and include a source when possible. Accepted material corrections update this register; cosmetic edits do not reset a dataset's verification date.
