How to Use Sold Card Comps in Precision Grade AI
Turn sold evidence into a documented value range by matching card identity, condition, date, and sale context.
The short answer
Use sold comps only after confirming the exact card and likely condition. Save multiple relevant transactions, remove mismatches, note sale dates and formats, and choose a value range that reflects both price and liquidity.
Why this matters
Good collection decisions depend on accurate identification, condition notes, acquisition cost, comparable sales, and a record of what changed over time.
A practical process
- Open or create the exact card record.
- Verify variation and condition fields.
- Review relevant sold evidence and exclude mismatches.
- Save the defensible range and confidence level.
- Refresh when the market or card condition changes.
Mistakes to avoid
- Selecting the highest result
- Mixing raw and graded cards
- Ignoring sale date
- Treating one auction as permanent value
Where Precision Grade AI fits
Precision Grade AI keeps market evidence, condition research, and portfolio tracking on the same record, reducing the chance that a detached screenshot becomes a misleading valuation.
Decision guidance: When the comp set is weak, display a wider range or no estimate. Honest uncertainty is better than false precision.
