Authentication Checklist

Evidence to collect

  • Pest Control documentation for Banksy works, plus documented event provenance for Dismaland-linked material.
  • Clear front, back, signature, numbering, label, and condition photos.
  • Seller chain, purchase history, prior auction record, or gallery documentation where available.
  • A certificate reference that can be verified independently, not just a loose paper COA.

Fake warning signs

  • Photos avoid the signature, edition number, reverse, packaging, or certificate.
  • The seller describes the piece with vague language instead of exact edition and provenance details.
  • The asking price is dramatically below the data-backed median without a condition explanation.
  • The certificate cannot be matched to the object being sold.

Price Data as a Diligence Tool

The market median is not an appraisal, but it is useful for screening risk. For Banksy, the current comp cut shows a median around $275. A listing far below that level deserves more proof, not less.

Collector FAQ

What is the first thing to check on Banksy?

Start with provenance and documentation. For this category, Gauntlet prioritizes Pest Control documentation for Banksy works, plus documented event provenance for Dismaland-linked material.

Can a low price be a fake warning sign?

Yes. A price far below the repeatable median should trigger extra diligence, especially when documentation is vague or photos are incomplete.

Does Gauntlet issue a COA?

Gauntlet documents each listed piece through gallery records and, where applicable, third-party or artist-issued authentication references.

Source: Gauntlet internal market-intel dataset and public auction context. Banksy claims require Pest Control documentation; Dismaland material is treated separately from authenticated Banksy prints.
