Black 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 black 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFolder has slight crease in cover, notes uneffected\u003c\/p\u003e","brand":"Fenix Collectables","offers":[{"title":"Default Title","offer_id":52289118404896,"sku":null,"price":250.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/2698\/1664\/files\/20260901-212100.jpg?v=1788261746","url":"https:\/\/www.fenixcollectables.com.au\/products\/10-block-of-four-1997-npa-folio-black-serial-copy-1","provider":"Fenix Collectables","version":"1.0","type":"link"}
