n.— «The first Supernote became known as Parent Note (PN) 14342. The term “Supernote”—also occasionally seen as “Superdollar” or “Superbill”—originated outside of the Secret Service. It refers to all high-quality counterfeits that can be linked back to PN-14342 with forensic evidence.» —“What Are Supernotes?” by Daniel Engber Slate Aug. 23, 2005.
