I'm coming up dry on this thing as well. However, things like this back in the day were most often bronze or brass, not copper. It also could have been some sort of souvenir medal, given the disturbance above the eagle's head on the reverse as @Spence noted in his response, which corresponds to that notch on the obverse. Lastly, never assume something isn't worth anything just because it's not silver or gold. Rarity is everything, and you'd be surprised at how many tokens struck from aluminum (often called "new metal" at the turn of the century back then, and often came from World's Fairs) are worth a tidy dollar today. Matter of fact, in 1903, St. Louis was the site of a world's fair, so that might be a clue for its origin to research. World's fairs were notorious for churning out all sorts of things like this. So until you know for sure what you've got, don't be too quick to junk-heap it.
