Since their inception in China, banknotes have become an integral part of the world’s monetary system. A banknote is essentially a promissory note—an instrument that guarantees the bearer a specific amount of money on demand. Historically, this promise was backed by precious metals, particularly silver or gold. Today, however, most currencies are no longer tied to metal reserves and are instead guaranteed by the issuing government.
In the Philippines, banknotes have a rich and diverse history dating back to the Spanish colonial era, making them highly appealing to notaphilist collectors. This diversity stems from the country’s political transitions as well as ongoing efforts to improve security features and prevent counterfeiting. Since Philippine independence, the Bangko Sentral ng Pilipinas has issued six major currency series:
Compared to coins, banknotes are more fragile since they are commonly made from cotton-linen blends. In the Philippines, advancements in technology have led to a shift from cotton-linen substrates to polymer banknotes, offering improved durability and security.
For many serious notaphilists, collecting doesn’t end with acquiring a full set of denominations. The real excitement comes from going beyond denominations and discovering varieties in Philippine Republic banknotes, including signature combinations, security upgrades, color variations, printing changes, and other features that make each note unique.
Let’s take a closer look at some of these remarkable types and varieties.
1. Banknote Printers / Security Printers
When the Central Bank of the Philippines was established in 1949, it did not yet have the capability to print its own banknotes. As a result, Philippine paper money was outsourced to foreign security printing firms. From the English Series through the Pilipino Series, these companies were responsible for producing banknotes:
SBC – Security Banknote Company
WSL – Waterlow & Sons Limited
TDLR – Thomas De La Rue & Company Limited, London
G+D – Giesecke & Devrient
With the exception of SBC—which printed its company name directly on the notes—these printers can often be identified through the range and style of serial numbers they used. For more details, you may refer to numismatics.ph.
2. Serial Number Color
This is a detail many collectors overlook. From the ABL Series up to the NDS, Philippine banknotes were printed with either black or red serial numbers, creating simple yet collectible varieties within each issue.
3. BSP Seal
Since 1949, the seal of the Bangko Sentral ng Pilipinas has undergone several revisions. Each official change affected the design of banknotes, resulting in varieties within the same series. Depending on the year of printing, you may find notes of identical design but bearing different BSP seals.
4. Color and Design Variations
These variations are often subtle but significant. While the overall design may remain the same, minor updates can occur across print runs, such as:
adjustments in the placement of serial numbers or BSP seals, addition or removal of certain text, small changes in engraving details, or slight color shifts compared to earlier releases.
These changes create collectible subtypes within a series, even if the main design stays consistent.
5. Signatures
Signatures are an important variety for collectors. A Philippine banknote typically carries the signatures of the incumbent President, and the sitting BSP Governor.
As these officials change, they create multiple signature combinations within the same series and denomination, making signature collecting a popular aspect of notaphily.
6. Serial Number Varieties
While every serial number is unique, certain special or patterned serial numbers are highly sought after. Examples include:
A000000, 0000001, ABC11111, repeating, ascending, or “radar” numbers
solid numbers (e.g., 555555)
“ladders” (e.g., 123456)
These notes often command premiums due to their distinctive and memorable sequences.
7. Commemorative Issues
Commemorative banknotes are among the most popular collectible types. The first appeared on the ₂ Piso note in February 1981, featuring an overprint marking a special event.
Unlike commemorative coins, which have clearly published mintages, commemorative banknotes are typically part of regular print runs, making it difficult to determine how many were produced.
To date, the Philippines has issued only two oversized, high-denomination commemorative banknotes:
1998 Centennial Commemorative Notes (2000 Piso and 100,000 Piso)
2021 Lapulapu Commemorative Banknote (5000 Piso)
These special issues are highly desirable among collectors.
8. Star Notes (Replacement Notes)
Star notes are replacement banknotes printed to substitute misprinted or damaged sheets during production. Because defective notes occur infrequently, replacement notes are relatively scarce and often highly valued by collectors.
9. Error Notes
Error notes are banknotes that passed through production and quality control with mistakes intact. Genuine error notes can be extremely rare. One of the most famous Philippine examples is the 2005 ₱100 banknote, where the surname of then-President Gloria Macapagal Arroyo was misspelled as “Arrovo.”
10. Specimen Banknotes
A specimen banknote is an officially issued sample note, marked to prevent circulation, used for reference, training, or design approval—and highly collectible today. These often carry SPECIMEN overprints, zero serials, or special perforations.
Philippine banknotes offer endless opportunities for discovery, from subtle variations to historic commemoratives. Whether you’re a beginner or a long-time collector, exploring these details adds richness to the hobby.
