Though Silver Eagles are mostly found in coin form, they can also be collected by picking up wallets, purses, and cash bags as well as silver and gold bars. Locked safes contain several hundred of these coins inside. Though most commodities can be bought with just a few Silver Eagles, permanent upgrades to weapons and Vigors through the Minuteman's Armory and Veni! Vidi! Vigor! vending machines respectively are far more expensive.
