The Philippine peso has witnessed a fascinating journey in its history, marked by various denominations and redesigns. Among these, the 100 peso bill has been a beacon of interest for collectors and enthusiasts alike, especially the older versions. If you're curious about the value of old 100 peso bills in the Philippines today, let's delve into this topic, exploring their history, current value, and collectibility.

Before we dive into the specifics, let's set the context. The Philippine peso was established in 1854, with the first peso bills issued in 1908. The 100 peso bill was first introduced in 1951, and since then, it has undergone several revisions, with the most recent one being in 2010.

Historical Value of Old 100 Peso Bills
The value of old 100 peso bills can be measured in two ways: their original purchasing power and their current collectible value.

Original purchasing power is a fascinating study. For instance, a 100 peso bill from 1951 could buy you five kilos of rice, while the same bill today buys only around two and a half kilos. However, it's important to note that this is primarily due to inflation and the increased cost of living, not a decrease in the bill's inherent value.
1951 Series "A" 100 Peso Bill

The 1951 series "A" 100 peso bill is one of the most sought-after versions. Introduced during the term of President Elpidio Quirino, this bill features a portrait of Andrés Bonifacio on the obverse and the coat of arms on the reverse. Its current collecting value ranges from 300 to 1,000 pesos, depending on its condition.
Incidentally, this bill is also known for its color-changing ink, a marvel of security features in its time. When viewed at different angles, the '100' written on the ink turns from orange to green, adding to its collectability.

The 1985 series, issued during the administration of Ferdinand Marcos, is another popular collectible. This series introduced several security features, including a watermark and holograms. Today, a well-preserved bill from this series can fetch around 500 to 1,500 pesos in the collecting market.
This series also witnessed a popular myth, with some people believing that the portrait of carboxylase on the reverse looked like former First Lady Imelda Marcos. While the Bangko Sentral ng Pilipinas denied this, it didn't deter collectors from seeking out this series.
