1 Peso Emilio Aguinaldo, copper pattern

This copper striking is a pattern produced during the Central Bank's redesign deliberations in the late 1960s, when the Philippines was evaluating a new circulating peso series that would eventually be issued in nickel-brass. Aguinaldo, who had died just eight years earlier in 1964 at the age of 94, was still a politically charged figure — his collaboration record during the Japanese occupation remained openly debated, and placing him on a circulating coin was not without controversy.

The copper composition was ultimately rejected in favor of more practical alloys. Few pattern strikes are documented, and most known examples passed through a small number of Philippine collector estates before reaching the international market.
