Tier 1
Direct transaction or transfer evidence
Usually the strongest starting point because it records the legal or practical event by which ownership changed hands.
Typical evidence
- Named and itemised invoice
- Auction-house invoice or settlement statement
- Marketplace order record
- Signed private-sale agreement
- Probate distribution document
- Formal gift or transfer document
- Import or customs record linked to the item
Collector judgement
The more precisely the document identifies buyer, seller, date, item, price and unique identifier, the more work it can do. A generic receipt for ‘collectibles’ is materially weaker.
