This a silver coin of the 1912 S Philippines Centavos Stars and Stripes
This was when the Philippines was a part of the US territories and we made all their coins for them and it had the United States of America on the coins.
The Philippines became US Territories in the year 1898 as a result of the Spanish American war. It remained in out territories until after WWII and became its own independent nation.
It was a part of our territory from 1903 to 1945.
The diameter of this coin is just a little smaller then a normal US dime. I would say some where around 17mm?
