Definition
An estate collection is any collection of memorabilia that has passed (or is passing) through an estate — typically due to the death of the original collector. Estate collections are a major source of standout items entering the market, but they're also where the most underselling happens.
Why it matters
Estate timelines pressure families into rapid decisions, and dealers know this. Slowing down 30–90 days for triage and appraisal almost always lifts realized value.
Example
After a long-time collector's passing, his family contacts an auction house. The collection is photographed, inventoried, and routed: standouts to auction, bulk to estate sale.
