Many replicas and souvenirs are known to exist. There are three series for the Philippines. A total of seven notes in the first series, four notes in the second, and two in the third series for a total of 13 notes of general issue. However, block variations, overprints, counterfeits, propaganda, advertising and other variations can make this group of notes very expansive. All have the Rizal monument vignette.
Some notes have serial numbers while others have a two digit block number only.
The third series was the result of severe inflation. The 100 Peso is considered rare and not considered a part of the series for most collectors. Military Payment Certificates MPC collecting began in 1946 with the first issues of series 461. However, most MPC collectors begin their collections with series 461 and continue through series 692. There are 13 different series and some 90 notes that make up a complete set.
