1931 5 Centavos United States Filipinas

At the time the Philipines was a US territory, so US-Filipino coins were minted for commerce over there. What you have is normal.

It's a common find. Especially since a good amount of Philippines coins were brought back to the US by servicemen after WWII. This is a piece from when the US administered the Philippines directly, that's pre-commonwealth (commonwealth meaning the transition period to Independence). The obverse crest shows that in that it uses a version of the Union Shield, whereas commonwealth coins show a localized heraldic shield. On the reverse is a depiction of a man with an hammer and anvil in front of Mt. Mayon, which is the standard reverse image for all one and five centavo coins well into the 1960s.

The mintage figure for this is 3,477,000, which is second only to 1932M in terms of 5 centavo pieces of that era. The book value of this coin in VF condition is $2.70. In terms of metal content, it's about 4.75g of copper-nickel. So, hope that gives you an idea of the value.

By the way, welcome to the forum, I noticed it's your first post.
