$10 Block of Four 1997 NPA Folio (Red Serial)

Acquire this distinguished $10 block of four from 1997, presented in an NPA folio with the prized red serial specification. Red serials from the late 1990s represent a distinct printing variant with restricted circulation, making authenticated examples highly desirable within the numismatic market. The block format maintains original presentation integrity while the Note Printing Australia folio ensures institutional authentication and archival-quality preservation standards. The 1997 $10 denomination holds particular significance within Australian currency documentation, and securing a red serial block elevates collector credentials substantially. An exemplary piece for those specialising in 1990s currency variants, red serial collections, or building comprehensive $10 series documentation with verified provenance and professional curation from this notable production period.
