Zimbabwe 100 Trillion Dollar Note: Security Features and Counterfeit Detection
The safest checks are the patterned security thread and the color-shifting Zimbabwe Bird printed in optically-variable ink. The note has no watermark, so looking for one proves nothing.
Last updated: July 2026
This reference covers the documented security features of the genuine 2008 Zimbabwe 100 trillion dollar note (Pick P-91), the common counterfeit tells that fail those checks, and why the "watermark test" circulating online does not apply to this note. The 100 trillion is the highest-denomination banknote of the modern era, with fourteen zeros, dated 2008 and released in January 2009.
Genuine Security Features
The Reserve Bank of Zimbabwe printed the trillion series under international sanctions, so the note carries fewer high-tech features than a modern U.S. bill. Two primary features authenticate the genuine note: the patterned security thread and the color-shifting Zimbabwe Bird. Both are documented in Wikipedia's entry on the note.
| Feature | Genuine Note | Common Counterfeit Tell |
|---|---|---|
| Patterned security thread | Metallic thread embedded in the paper running vertically down the left side of the front, with repeating RBZ (Reserve Bank of Zimbabwe) lettering visible at an angle | Thread is printed flat on the surface, lacks metallic sheen, or lettering is blurry and unreadable |
| Color-shifting Zimbabwe Bird (optically-variable ink) | The Zimbabwe Bird emblem in the lower right of the front shifts between gold and bronze tones when tilted under a light source | Bird is a single flat color (usually gold) that does not shift at any angle |
| Chiremba Balancing Rocks (front design) | The front depicts the Chiremba Balancing Rocks near Epworth, outside Harare, with fine line detail | Image is blurry, pixelated, or shows incorrect subject matter |
| Intaglio (raised) printing | Serial numbers and key denomination text have a slightly raised texture you can feel with a fingertip | All ink is perfectly flat, typical of inkjet or laser printing |
| Serial number format | Red and black serial numbers in a consistent font, two-letter prefix (AA most common, AB and AC documented in smaller quantities) | Mismatched fonts, uneven spacing, or identical serials across multiple notes |
| UV-reactive inks | Under UV blacklight in a dark room, the note body fluoresces and security elements glow distinctly | No reaction (foil replicas) or bright paper-white glow (office paper reprints) |
| Paper substrate | Cotton-based banknote paper with a firm, slightly coarse feel | Metallic foil, plastic, glossy photo paper, or thin office paper |
The Watermark Myth
The Zimbabwe 100 trillion note has no watermark. Wikipedia states the note "lacked modern security features, such as a watermark" because of sanctions against Zimbabwe at the time of printing. Some online guides instruct buyers to hold the note to light and look for a watermark, but this test does not apply to Pick P-91.
Why does this matter? If you are expecting a watermark on a genuine note that never had one, you might reject authentic currency. Conversely, a counterfeiter could print a fake watermark onto a reprint, and a buyer relying on the watermark test alone would be fooled.
Bottom line: Do not use the presence or absence of a watermark as a deciding factor. Authenticate by the patterned security thread, the color-shifting Zimbabwe Bird, and the raised intaglio printing instead.
Fastest Way to Be Sure
Buy a note already authenticated by PMG or PCGS. Both grading services authenticate every note before assigning a grade on the 1-70 scale, then seal it in a tamper-evident holder with a unique certification number. You can verify that number yourself:
- PMG: Enter the cert number at pmgnotes.com/certlookup and confirm the description matches.
- PCGS: Enter the cert number at pcgs.com/cert and do the same.
If the lookup result does not match the label, or the number does not exist, the holder may be counterfeit. Learn more in our Banknote Grading Guide.
Alternatively, buy from a source-first dealer that inspects and guarantees every note. Planet Banknote sources direct from mints, central banks, authorized distributors, and trusted consignors. Every note passes our Planet Banknote Verified inspection process and ships with a free Certificate of Authenticity. Our Lifetime Guarantee covers authenticity for as long as you own the note.
Gold Foil Replicas Are Not Counterfeits
The most common source of confusion is not a counterfeit at all. Shiny gold, silver, or colored metallic-foil "100 trillion dollar" notes are sold openly on Amazon, eBay, and Etsy as novelty souvenirs. They were never printed by the Reserve Bank of Zimbabwe. If a note is metallic, plastic-feeling, or gold all over, it is a novelty item worth a few dollars at most.
These replicas often ship with their own printed "certificate of authenticity," which certifies only that you bought a souvenir. Some invent denominations that never existed. The genuine Zimbabwe 100 trillion note is printed on cotton banknote paper, not foil or plastic.

Frequently Asked Questions
Does the Zimbabwe 100 trillion note have a watermark?
No. Wikipedia states the note "lacked modern security features, such as a watermark" due to sanctions. Do not rely on a watermark test to authenticate Pick P-91. Use the security thread and color-shifting Zimbabwe Bird instead.
What is the single most reliable test for a genuine 100 trillion note?
The tilt test on the Zimbabwe Bird. Hold the front of the note flat, then tilt it toward and away from a light source. The Zimbabwe Bird in the lower right must shift between gold and bronze tones. Fakes and foil replicas show a single flat color with no shift.
Can a gold foil 100 trillion note be real?
No. Gold, silver, and colored metallic-foil "100 trillion" notes are novelty souvenirs sold on Amazon, eBay, and Etsy. The Reserve Bank of Zimbabwe never printed foil currency. Genuine notes are cotton-based banknote paper.
How can I verify a PMG or PCGS graded note is authentic?
Look up the certification number. Enter the number on the holder's label at pmgnotes.com/certlookup (PMG) or pcgs.com/cert (PCGS). Confirm the description and grade match. If the lookup fails or the details do not match, the holder may be counterfeit.
What is on the front of a genuine 100 trillion note?
The Chiremba Balancing Rocks near Epworth, outside Harare. The front does not depict Robert Mugabe, a rhinoceros, or any other wildlife. Fine line detail should be crisp under magnification.
