What the term means
Multi-disc sets, booklets, inserts and limited packages. The term should be supported by label, catalog, matrix, packaging and provenance evidence rather than seller enthusiasm.
Identification checks
- Inventory every component.
- Outer-box condition matters.
- Replacement discs can create mixed sets.
Condition and market
Compare equivalent copies with the same pressing type, country, completeness and condition. A rare format can still have limited demand, and a later pressing can sometimes outperform an original because of sound, packaging or availability.
