the Philippines' first Commonwealth President and General Murphy and U.S. President Franklin D. Roosevelt. A new design for the reverse based on the seal of the Commonwealth he designed was also introduced on those commemoratives, and featured on all Philippine coins minted from 1937 until 1946. When Philippine coinage production resumed in 1944, the One, Five, and Fifty Centavo pieces were again struck in San Francisco (complete with "S" mintmark), Five Centavo pieces were also struck in Philadelphia (no mintmark), and the Ten and Twenty Centavo pieces were struck in Denver, introducing the "D" mintmark to Philippine coinage. All of these coins featured the new Commonwealth reverse design. On July 4, 1946, the era of the Commonwealth ended as independence was granted to the Philippines as a sovereign nation.
