Our principles
- Helpful first: We aim to answer the question a collector has (identify, authenticate, value, sell) with practical steps.
- Data-supported: When we discuss price ranges, we reference real auction comps where possible.
- Honest uncertainty: Many items cannot be priced confidently without condition and provenance details; we say that clearly.
- Continuous improvement: Guides are living documents and are updated as data and best practices evolve.

Not sure if your item is worth appraising? Let us take a look.

Free. No card needed. Takes about two minutes.
Writing & review
- Research: We review reference sources (museum/auction glossaries, standard identification criteria, and market context).
- Drafting: We use structured templates (checklists, decision trees, comparison tables) to keep content actionable.
- Review: We sanity-check key claims, pricing drivers, and comp citations before publishing.
- Updates: We update guides when auction data changes materially, new counterfeits emerge, or readers flag issues.
Corrections
If you believe a guide contains an error (incorrect attribution criteria, wrong terminology, broken link, or outdated claim), please contact Appraisily support with the URL and a short description of the issue. We review and update the page when appropriate, and the “Last updated” date will reflect significant revisions.
Internal linking & crawlability
We maintain internal links between related guides to help readers discover adjacent topics and to help search engines crawl the site more consistently. Related links are intended to be helpful, not to manipulate rankings.
