the phillippines were a US owned / controlled "territory" gained from spain in the spanish american war settlement (early 1900's * era ) --the japanese invaded in 1941 about the same time as when they bombed pearl harbor * many us & filipino soldiers were trapped and captured and put on the infamous battan death march * - when the us troops returned to the phillipnes in 1944 they brought us minted coins with them like the 1944 "for phillipines use" dime made in the us mints * after WW2 the phillipines became a "indepedant nation" and was not a us territory anymore -- although for a long time afterwards there was a large us military base there -- subic bay * which was used heavily during the veitnam war --it has since closed.
offically your coin is a us minted - us territory coin * it is 750 silver --or 75% silver
