Sealed-collectible guide

Records for Selling a Sealed Collection

Receipts, basis, fees, shipping and professional tax advice.

Factory-sealed collecting rewards careful identification and restraint. The same visual sign can be normal on one product and suspicious on another, so category-specific comparison matters more than generic “reseal tricks.”

1. Keep purchase records

Keep purchase records should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

2. Record sale dates

Record sale dates should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

3. Track fees

Track fees should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

4. Document inherited property

Document inherited property should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

5. Ask a tax professional

Ask a tax professional should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

Preservation rule: Do not open, peel, puncture, heat, rewrap, flatten or chemically treat packaging to test authenticity or improve appearance.
