Asking Prices Versus Completed Sales

Why optimistic listings do not establish artifact value.

Ancient artifacts are not ordinary secondhand goods. Their archaeological context, lawful movement, ownership history and physical stability can be more important than immediate market appeal.

1. Unsold is not value

Unsold is not value should be documented against the exact physical object, likely source jurisdiction, ownership timeline and conservation condition. Record uncertainty rather than replacing it with a confident market phrase.

2. Match provenance quality

Match provenance quality should be documented against the exact physical object, likely source jurisdiction, ownership timeline and conservation condition. Record uncertainty rather than replacing it with a confident market phrase.

3. Exclude doubtful objects

Exclude doubtful objects should be documented against the exact physical object, likely source jurisdiction, ownership timeline and conservation condition. Record uncertainty rather than replacing it with a confident market phrase.

4. Use several sales

Use several sales should be documented against the exact physical object, likely source jurisdiction, ownership timeline and conservation condition. Record uncertainty rather than replacing it with a confident market phrase.

Due-diligence rule: Authenticity does not prove legal title, and a negative stolen-object search does not prove lawful export.
