50 Kina 25 Years of Independence

Papua New Guinea's 25th independence anniversary fell in September 2000, and this commemorative 50 Kina was among the early polymer issues from the Bank of Papua New Guinea — a relatively swift adoption of the substrate given that Note Printing Australia had only been producing polymer notes commercially since the late 1980s. The optically variable ink on this note was a meaningful addition for a Pacific nation where note authentication infrastructure outside Port Moresby was limited.

Pick 25 is moderately scarce in genuinely uncirculated condition; commemoratives of this type often entered informal circulation in rural areas rather than being preserved by the recipients they were distributed to.
