About This Data
These figures reflect InstAppraisal's archive dataset — historical appraisals and derived valuations submitted by our community. Where external sold-market data is available, it's shown separately as "Market." AI-generated text provides interpretation and context only.
Data Sources
- Archive (Internal): Historical appraisals from InstAppraisal users, including AI-assisted valuations and expert comments from trusted appraisers.
- Market (External): When available, sold prices from auction houses and secondary markets. Currently limited.
- AI Overview: Generated commentary that interprets archive data — not a source of pricing data itself.
Important Limitations
- Trends are based on available data and may not represent the broader market.
- Categories with fewer than 10 items have limited statistical reliability.
- Individual item values vary significantly based on condition, provenance, and market timing.
- Historical trends do not predict future values.
