There are many ways in which private mints produce silver bullion bars. The two most popular options in silver bars are minted ingots and cast silver bars. The former requires more work to produce and results in higher premiums over the spot price of silver, while the latter has lower premiums and takes less effort to manufacture. The primary difference between minted ingots and cast bars, beyond the visual aspects of each, is the production process. Minted ingots take more time and go through more steps from raw silver to a finished product. The minting process requires more steps and results in more intricate designs, but also higher premiums compared to the spot price. Cast silver bars undergo a process similar to the production of jewelry. The metal is poured into a heat-resistant mold once melted and enclosed within that mold to form the preferred shape the refiners are looking to create. In this case, the result is a silver bar that has a rectangular shape with smooth edges and matte surfaces. On the obverse side of 10 oz Eagle Cast Silver Bars is a depiction of the bald eagle. A member of the sea eagle species, it is one of two subspecies that forms a species pair with the white-tailed eagles. The bald eagle shown here is swooping down on its pretty with its talons outstretched ready to strike and its wings extended to slow its descent from the air down to the ground. Inscriptions on this side of the bar include the weight, purity, and metal content.
