10 Centavos Dotted border, series at right

The Mindanao Emergency Currency Board was one of several provincial and local bodies that printed guerrilla currency during the Japanese occupation of the Philippines. These notes were produced to maintain a functioning local economy in areas under Filipino-American resistance control, deliberately kept out of Japanese hands and emphatically rejected by occupation-era military scrip.

The dotted border variant distinguishes this from otherwise similar issues in the S512 series — a subtle but cataloged difference that suggests sequential production runs under constrained printing conditions, where small design alterations marked new batches rather than new denominations.
