Apollo Era Authentication Guide
Authentication checklist for Apollo Era: documentation, certificate standards, signature or edition checks, condition review, and price-data warning signs. This page is built for collector diligence: what to verify before purchase, where fakes usually fail, and how price data helps flag suspicious listings.
Authentication Checklist
Evidence to collect
- mission specificity, astronaut signature provenance, Zarelli-style review where relevant, and item-level documentation.
- 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 Apollo Era, the current comp cut shows a median around $425. A listing far below that level deserves more proof, not less.
